Beautiful Tears with Makoto Fujimura

Learning to see and appreciate beauty more has been one of the greatest joys of my time at Grove City. I had Civilization and the Arts with Dr. Drake my sophomore year, and it was an amazing class. We studied many great works of art and music and I learned the discipline of simply looking, of listening, of actively receiving art.

Charis-Kairos (The Tears of Christ) by Makoto Fujimura

I remember when Dr. Drake talked about the work of Makoto Fujimura. And I recently heard him speak on campus as part of the 2017 Christian Writers Conference. It was amazing.

Mr. Fujimura opened by declaring that we need to see culture as a garden to steward and as a world of abundance instead of one with limited resources. He suggested that the only cultures which struggle to see abundance are Western ones which have learned to measure success in limited resource models in the wake of the Industrial Revolution. Christians with a “culture war” mentality have not been helping.

There is not enough time in a short post to share half of what Mr. Fujimura shared with us – I wish I could find a video recording of his address. A few things were particularly striking to me, though.

The art on the right was commissioned by Crossway and is based on the shortest verse in the Bible: “Jesus wept” (John 11:35). Mr. Fujiumra spent a significant part of his time sharing the background of that verse with us, and what he believes we should learn from it.

In John 11, we find the story of Jesus’ delayed coming, Lazarus’ death, the dismay of Mary and Martha, and the resurrection of Lazarus. The wisdom of Jesus is revealed in the way he interacted with Mary and with Martha; although they both said the same thing to him, he gave words to the analytical Martha but tears to Mary.

So we learn that the gospel is about tears.

In John 12, Mary is found anointing the feet of Jesus, wasting a pound of expensive ointment. Judas is outraged — the money should have been given to the poor. Judas didn’t understand until it was too late, but the gospel is not pragmatic.

We ought to waste our very best on Jesus.

Finally, Mr. Fujimura suggested that we ought to live more like Lazarus, who did absolutely nothing. He just died. But if Christians lived like Lazarus, with absolute confidence in God and deep joy in our relationship with Christ, how would that change our culture?

The gospel gives us confidence to “chill out” with Jesus.

If the American church understands this, perhaps we will have a culture of abundance.

Building a Mobile Robot

As part of the mobile robotics class being offered next spring, Grove City engineers are designing a new robot. The hardware looks amazing, with components like National Instruments’ myRio, Garmin’s LIDAR-Lite, an inertial measurement unit, and a GPS. The robot will be equipped to navigate the outdoor world, and it will be up to the students to program it.

What I also think is cool about the robot is the team working on it. Dr. Mohr is teaching the mobile robotics class and so is leading the project, but developing the robot spans both the Electrical Engineering (EE) and Mechanical Engineering (ME) departments. A senior ME, Joel Bodine, has been designing the chassis as part of an independent study with Dr. Archibald. And Mr. Jaillet, the EE lab technician, has been essential to the project’s success, helping with practical details from his years of experience with electronics and design.

Joel Bodine - New Robot
Joel presenting the latest design concept

All of the ME students become masters of Creo by senior year, and that was clear with Joel, as he used the software to model every aspect of the chassis and then knew how to present from the model. But Joel had also learned a lot about designing for production and was able to draw on that experience. For instance, Grove City owns two 3D printers, which Joel will use for creating the chassis, so along with functional evaluation of each chassis design comes a consideration of how feasible printing each design is.

I learned a few things from observing the meeting. For instance, if you’re designing a robot for the outdoors, you should make sure you have good ground clearance; no one likes it when their robot gets stuck going over a hump. There is also a lot more to designing a chassis than is apparent: You can’t forget details like how the charging cord will connect to the battery charging port or how the wires will go where they need to go. There is also a lot of room for creativity, as was obvious from the different concepts Joel had developed.

Over the summer, Dr. Mohr will be working out some of the details of class projects for the mobile robot, but expects students to use the robot for things like localization (finding where you are and mapping the environment) and an interactive game.

Dr. Mohr also showed me the circuit schematic he has been working on, which is impressive. It’s also a lot neater than the one I made recently for his PCB design class. (Side note to future EE’s: You should definitely take the PCB class. It’s offered occasionally as a one-credit special topic class. I am learning so much about designing everyday circuits that I probably wouldn’t have otherwise learned with my computer concentration, and PCB’s are really cool.)

Robot Schematic

And there you have it! Future engineers at Grove City will get to program this mobile robot which is currently being designed and produced. And future students who, like Joel, have an interest in independent research, will get to continue working on the cutting edge of Grove City’s engineering program.

Student Profile: Graham Allen

Graham Allen is a junior Mechanical Engineering major who is known for encouraging and exhorting his peers to use their gifts with excellence in pursuit of Christ and his kingdom. He is a very genuine guy and a lot of fun to be around, and I appreciate his willingness to answer a few questions for those of you making decisions about college.

Why Grove City College?

In high school, Graham applied to four colleges and Grove City College was the only Christian one. He was primarily looking for a school where he could be academically challenged, run track, and continue studying Chinese.

So on a utilitarian level, Grove City College was a good choice because he could do all of those things. But Graham was really wrestling with whether to go to a secular or Christian college; he had been to a secular high school and had felt called to that then.

Graham attributes his decision to the Admissions team and to the peace he had about choosing Grove City. He was struck by their spirit of prayer for all applicants regardless of where they would be led and developed a good friendship with Zach Jew. When he visited the campus, he also sensed a vitality and spirit at Grove City when he visited that he hadn’t sensed at the other schools he had visited.

You had some expectations coming to Grove City College. How did those compare with reality?

Graham says his experience has been richer than he could have expected. Referencing Romans 12:1, a verse engraved on the outside of the Student Union, he says his mind has been renewed, especially in terms of priorities. He came to Grove City to focus on academics and run track, and while he has been able to excel in both, God has also reoriented his priorities and he has learned not to idolize school or vocation.

What have you been involved with on campus?

Graham served on SGA last year. He is currently one of the captains of the track team, a member of AEX (a housing group), and a researcher in Dr. Anderson’s lab. Lately he has also been involved in planning a missions conference.

Can you tell me more about the missions conference?

Last year, a large group of Grove City students went to the Urbana Conference. Graham was particularly struck by the largeness of God and the fact that the American church is only one small facet of the Church. We need to find our place and not see ourselves as the top.

Graham talked to Dr. Keehlwetter, who has been hoping and praying for years for an organic missions focus at Grove City. Graham is excited about the interest on campus and hopes that the conference (March 20-24) will help give us a larger view of God and understand our context as a Christian college.

What are your future plans?

Like most of us, Graham has had a number of ideas about vocation. Coming in, he thought engineering might be preparation for seminary. Having learned more about the Reformed doctrine of vocation, he’s still praying about seminary and international ministry but would currently like to work for a Christian engineering firm when he graduates.

What thoughts do you have for prospective students?

First and foremost, dedicate the process to prayer and expect God to answer, even if it’s at the last minute.

Second, when looking at a college, consider that it will be the place you live. Think of it as a home where you will experience all the normal things in life – joy and sadness, ups and downs, triumphs and difficulties. Will this particular college be a place where you will be supported and challenged? Do you want to be like those around you? There is more to college than the credentials you get at the end.

* * *

This is part of a series of interviews I am conducting with current students who embody what I most appreciate about the College: Amazing peers who challenge me with their example, reminding me of the words of Paul to Timothy: “Let no one despise you for your youth, but set the believers tan example in speech, in conduct, in love, in faith, in purity.” (1 Timothy 4:12, ESV)

Thank you for reading, and to Graham for taking the time to talk!

Minor in Robotics

There is something undeniably exciting about robots. Christians in particular have good reasons to be excited, as well as a unique perspective. Instead of seeing robots as a replacement for the human race, or supposing that the ultimate “upgrade” is electronics hardware and artificial intelligence instead of a new heart1 (Ezekiel 36:26), we believe that the human race is crowned with honor, though we may not know why (Psalm 8), and we seek to use technology and robotics to empower humans.

As one example of how Grove City students are doing that, Logan MacKenzie (Computer Engineering ’18) spent last summer at the Milwaukee School of Engineering developing a low-cost, fluid-powered robotic arm for wheelchairs.

Grove City is further equipping students to serve in the robotics field with a new minor. The following new courses are coming for the 2017-18 academic year:

  • ROBO 301: Introduction to Robotics.
  • ROBO 302: Mobile Robots.
  • ENGR 301: Ethics in Engineering and Robotics.

Quanser RobotAlong with the new courses come new robots. Dr. Allison showed me a robotic arm Grove City purchased from Quanser last fall. The arm can be controlled via MATLAB for some interesting labs. For instance, how do you move joints simultaneously so that a hand moves in a straight path? Grove City is also looking to purchase a LR Mate robot soon.

This year, some senior mechanical engineers are building a dart-throwing robot for their senior design project. It uses a heavy-duty DC servo motor to throw the darts and is equipped with computer vision which can be used as feedback for the control system. Through their project, the seniors are also creating a hardware and software framework for future robots designed by underclassmen of both engineering disciplines.

Finally, Dr. Mohr, Mr. Jaillet, and Joel Bodine (Mechanical Engineering ’18) are designing a mobile robot for the ROBO 302 class. It should enable some fun labs and outdoor projects. A post with more information on the robot will follow.

Best of all (no pun intended), electrical engineering majors can graduate with a minor in robotics without any extra coursework since the robotics classes count toward requirements for the major!


1. Thanks to Dr. Dudt in biology for this helpful contrast. (Dr. Dudt teaches a section of Studies in Science, Faith, and Technology.)

Springbreakers: Engineers and Missions

How can I, as an engineering student, further the work of Christian missions? This is a question I’ve been asking for a while. Last week gave me part of the answer.

Spring break began after classes on Friday, March 3, and since I live close to home I was able to visit with my family that evening and all day Saturday. On Sunday, I drove back to Grove City to meet two other students and to leave for Elkhart, Ind., home of SonSet Solutions, where we served for the remainder of the break.

SonSet has been helping ministries start Christian radio stations for years, and has developed an affordable solar-powered radio (called a “SonSet”) which can be programmed to tune to local Christian stations. These are used all over the world and are being actively developed (the team is working on the next generation model now). However, their partner ministries increasingly have needs beyond radio. For instance, wells installed in Africa need to be serviced if they stop working, but sometimes ministries cannot easily access the wells (e.g., no roads, guerrilla groups, etc.). So SonSet created a water monitoring system that sends data via satellite.

SonSet Spring Break 2017
The first 2017 spring break team at SonSet.

When we arrived in Elkhart, we met our host families and the next day at work met all of the other students who were also spending their break at SonSet. There were 10 in total: three from Grove City, six from Cedarville, and one from Northwestern. SonSet would be hosting other students in following weeks.

Two Grove City students were working on a power protection unit that shuts off electricity if the power input is dirty (e.g., voltage spikes). Logan MacKenzie ’17 worked on the electrical design and Joshua Kuipers ’18 worked on the assembly.

SonSet Service ProjectIn addition to our project work with our mentors, we had a few events throughout the week, like our service project at Faith Mission where we served dinner to walk-in’s and cleaned some warehouse floors.

My project was to make a touchscreen device that reads debug messages transmitted over I2C. The main features I implemented were:

  • Different display states/screens
  • Touch buttons to transition between states
  • A view with a scrolling list of the most recent messages
  • A view with the most recent debug information displayed visually (e.g., gauges for water monitor information)

I recorded a short video on Friday to show the basic functionality. The Arduino is sending messages to the system over I2C with fake water monitor data:

What was exciting for me was to realize how much I have learned from Grove City College. I was drawing largely on my experience from classes like Embedded Systems with Dr. Walker. Of course, basic math was helpful when computing the corner points for the triangles on the gauges. Engineering is so much fun, and it was exciting to do a project with a very practical application for missions!

Student Profile: Bethany Haughey on the Great Conversation

Bethany Haughey is a junior English major with a wide variety of academic interests, from chemistry to history. She is minoring in biology. I recently had the opportunity to interview her about her experience at Grove City College, and we had a great conversation.

Why Grove City?

For Bethany, acceptance to the Trustee Scholar program made Grove City College the right choice. Of the seven schools she applied to, Grove City was the only Christian one. At the end of the day, she was excited about two main communities — the community of 2,400 students on campus seeking the mind of Christ and the smaller community of fellow Trustee scholars that she would join. To her, that was better than the Honors College at the University of Maryland.

How did you choose to study English, with so many academic interests?

One cannot get far on this campus without bumping into C.S. Lewis. Bethany referenced his introduction to Athanasius’ On The Incarnation where Lewis notes the importance of understanding the great conversation around us: “If you join at eleven o’clock a conversation which began at eight you will often not see the real bearing of what is said.”

For her, studying English is a great way to catch up on this conversation. But she values other disciplines too: History provides much-needed context, and theology and philosophy tell us what the conversation has said about the most important questions.

What about chemistry?

When Bethany graduated from Rockbridge Academy in Millersville, Maryland, she wouldn’t have identified as a science person — and she says she still wouldn’t, perhaps especially not this semester. But with such a strong background in the humanities, she wanted to explore science on the collegiate level. Since biology was her favorite science in high school, she has been taking the same classes that pre-med students would take.

She has also been doing independent research on polymers for DNA delivery.

Can you tell me about your research paper?

For Dr. Smith’s Civilization and the Speculative Mind (a HUMA core requirement often called “Spec Mind” by students), Bethany wrote a history research paper on the history of missiology. Studying 18th- and 19th-century China, she followed the development of missionary activity from imperialism, which imposed Western culture, to a more culturally-accepting approach characterized by Hudson Taylor. The paper grew out of her interest in China and in missions — her local church has done regular mission trips to Brooklyn for as long as she can remember, and her frequent participation has shaped her deeply.

Dr. Smith encouraged her to present at a conference, which she did, noting that she appreciates how pro-active faculty are in matching students with opportunities.

You have a longstanding commitment to Chinese as well?

Bethany’s mom is from Hong Kong, and speaks a dialect but not Mandarin. So since fourth grade, Bethany has studied the language and her proficiency was demonstrated recently when she placed third in the US East-Coast Chinese Bridge Chinese Proficiency Competition, where she gave a speech in Mandarin and played erhu, the Chinese violin.

What do you think of Grove City’s Orchestra?

Bethany played in the orchestra in high school and has continued as first violinist. She’s been in the main Orchestra since freshman year, and this year has also had the privilege of playing in the much-smaller Chamber Orchestra. She says it’s amazing how quickly everything comes together (e.g., there is a major October concert, after just two months of school), and that the campus commitment is remarkable. Around ninety students participate and there is always a good turnout for concerts.

What’s next, after Grove City College?

Grove City has really changed Bethany’s answer to this question and she finds herself torn between two paths. On one hand, she is considering medicine, as she enjoys working in the minutiae to serve others; but lately she has also been exploring the possibility of becoming a professor of literature. Her time at college has shown her how influential a good professor can be in a student’s life.

Regardless of what lies ahead, Bethany is confident that what she has learned at Grove City will continue with her, having made her a better person.

Do you have any advice to students considering Grove City College?

Two things: Talk to the students here, and talk to the professors. You will find a wonderful community. Bethany mentions her friends and freshman hall alongside the Trustee Scholars.

Any final thoughts?

Dr. Munson’s section of Civilization and the Arts (“Civ Arts”) is amazing. The HUMA core widens your perspective and allows you to see the context of where we are today on the basis of the past.

Bethany urges prospective and incoming students to think about what they want college to be. And if that vision includes being educated and influenced as a person, she urges them to take an active role. True education is both for the mind and for the soul.

This is part of a series of interviews I am conducting with current students who embody what I most appreciate about the College: Amazing peers who challenge me with their example, reminding me of the words of Paul to Timothy: “Let no one despise you for your youth, but set the believers an example in speech, in conduct, in love, in faith, in purity.” (1 Timothy 4:12, ESV)

Thank you for reading, and to Bethany for taking the time to talk!

Student Profile: Alicia VanDerhoof on Growing in Community

Alicia VanDerhoofAlicia VanDerhoof is a junior English major who recently agreed to sit down for an interview. I wanted to get her perspective on Grove City College because she knows this place well and has committed herself to the community, both on and off campus, and is a generally thoughtful person as well.

Why Grove City?

For starters, I asked Alicia why she chose Grove City, and was surprised that volleyball was part of the answer. Alicia was drawn to Grove City’s focus on the liberal arts and its classical studies minor, but she cast a broad net and applied to 10 colleges. As someone who had to finance her own education, cost played an important role. But when it came down to a final decision, she couldn’t play volleyball at the other school she was considering.

What are you studying and why?

Alicia hopes to teach in a classical school, and has been involved with the local one in Grove City. She chose English because it’s a major that involves literature and reading, but also writing and understanding history — all things that would be valuable for a teacher. She is also minoring in classical education.

How is English different at Grove City College?

We live in an age of “multiculturalism” which tends to reject one’s own heritage and replace it with a misplaced desire to appreciate all cultures equally well. In Alicia’s experience, the department does a great job of studying and emphasizing the Western Canon while still appreciating good literature wherever it may be found.

For instance, English majors take a year of American Literature with Dr. Messer and then a year of British Literature with Dr. Moore. Majors also take a Shakespeare course. At the same time, Dr. Waha teaches a class on African literature which her students love.

As Alicia noted, “You don’t want to sacrifice the good to be relevant to all.”

What do you enjoy reading, and how has college changed that?

Alicia’s “joy reads” are still catching up on the classics — she named Jane Austen, Mark Twain, and Charles Dickens as a few favorites. But she says that classes like the 20th Century American Novel have really stretched her, since they are novels that deal with completely different questions.

She also noted the helpfulness of having a professor to guide the reading and to bring a Christian perspective. Without this, for instance, reading those 20th century works could feel quite hopeless!

And finally, Alicia has appreciated the department’s sense of charity and eagerness to see common grace in literature. All truth is God’s truth. And it is precisely because the department holds to Scripture as the standard that other works can be appreciated for their merits and measure of truthfulness.

How have you been involved in the community?

Alicia said that she loves being involved outside the classroom, on and off campus, and proceeded to make that obvious.

On campus, she is involved with Lux Mea, a student society committed to fostering the community of learning between students and faculty of all disciplines. She is also a teaching assistant, or TA (something she heartily recommends to everyone!) and films for the men’s basketball games, something that has really made her a part of their team.

Off campus, she helps with the local classical Christian school (Grove City Christian Academy), working with the first grade. She said it’s great to be out of the college bubble and doing what she loves already. She’s also involved at Grace Anglican Church, where she attends, working with K-3 students. And finally, she helps out at Paper Sky Theatre, a local venue that puts on some incredible plays.

What professors have you found most inspiring?

Dr. Edwards (History): Having read widely and thought carefully, Dr. Edwards knows where he stands and so when he lectures, he deeply challenges the way you think. He also chooses readings that contradict each other, so you’re forced to determine what you believe. Alicia says everyone should take Historical and Philosophical Foundations of Education with him!

Dr. Potter (English, and Alicia’s advisor): Alicia appreciates his humility and his thoughtfulness in his comments. He helps students become better and more charitable readers so they can become better writers as well. She also noted that he attends Grace Anglican Church as well, and it has been valuable for her to see a professor outside of academia — getting his hands dirty and worshiping Christ in community.

Dr. Graham (History): Alicia took Latin with him and learned more about history and Western civilization than she expected! He is always wanting to learn, connecting dots in surprising and insightful ways. He even goes on regular archaeological digs!

Dr. Gordon (Biblical Studies): His pastoral background is sufficiently broad that he can joke that he only needs the Bible. He is a very wise man (and has written a few books) who is also hilarious, and generous in his office hours. Alicia notes that professors here are generally eager not only to answer questions but also to get to know students.

What final advice do you have for future college students?

Alicia exudes optimism for what college can be, and says that the community of professors and students is an encouraging one to grow in faith and in knowledge. She points out that one is not excluded from learning things outside one’s major, and that college is a time to learn what you really believe because you will be challenged.

And finally, she says to get connected to a local church and be involved outside the College — both things that she clearly practices as well.

* * *

This is the first of a series of interviews I will be conducting with current students who embody what I most appreciate about the College: Amazing peers who challenge me with their example, reminding me of the words of Paul to Timothy: “Let no one despise you for your youth, but set the believers an example in speech, in conduct, in love, in faith, in purity.” (1 Timothy 4:12, ESV)

Thank you for reading, and to Alicia for taking the time to talk!

My First March for Life

I woke up at 3:20 a.m. Not my normal wake-up time, I assure you. But I was meeting six other Grovers in the SAC at 3:45 and wanted to give myself enough time to get ready.

2017 March for Life

It’s been 44 years since Roe v. Wade, and so this past Friday, January 27, was the 44th Annual March for Life in Washington D.C.  My generation has never known another America.

The impact of that decision is breathtaking: Over 58 million babies have been aborted. That’s more deaths than can be attributed to the sum of all of America’s wars.

It has been a few years since Grove City’s Life Advocates went to the March. For many of us, myself included, it was our first March. And it was moving. There is something about giving up a day of your life, being on the ground, carrying a sign, trying to represent those that have no voice, getting a little more tired with each step and passing hour, and remembering that any small sacrifice we made was rather pale. Approximately one abortion is performed every two minutes in the U.S.; hundreds died even as we marched.

This year’s theme was “The Power of One.” Speaking for the Trump administration, we heard from Mike Pence and Kellyanne Conway. While past pro-life presidents have delivered video messages, this was the first March where an executive — a vice president — came to the March.

But I particularly appreciated Eric Metaxas and Rep. Mia Love, who spoke later in the rally. Metaxas boldly proclaimed the sovereignty of Christ and the way that his church should respond with grace and forgiveness toward her enemies. Rep. Mia Love gave us a more personal story about how her immigrant parents were inconvenienced by a pregnancy with a third child, but chose life. How could they have known then that she should become the first female African American Representative to Congress?

As the rally ended, and Bishop Vincent Matthews prayed for the crowd, thousands and thousands moved toward Constitution Avenue to begin the march to the Supreme Court and Capitol Building. When our group arrived, some time after 3:00, women who had had abortions were giving their “Silent No More” testimonies outside the Supreme Court. Each told of the pain they had experienced knowing they had killed their son or daughter, and the forgiveness they had finally found in Jesus — many through Bible studies in a local church.

I am glad that I went. I’ve always been “pro-life” — I am convinced, from Scripture and from science, that life begins at conception and I believe that human life is inherently valuable. But going to the March for Life underscored, in my own heart, how sad and serious this issue is. May the Lord be gracious to us and let us see an end to legalized abortion in our lifetime! We are the Pro-Life Generation.

Say Bonjour to Intercultural Friendships

Time, treasure, and talent — these are three areas of stewardship that often come to mind. But my dad always reminded me that there are other areas of stewardship, including one’s body, mind, spirit, and relationships. He told me not to underestimate the importance of relationships. As C. S. Lewis famously said in The Weight of Glory,

There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilizations – these are mortal, and their life is to ours as the life of a gnat. But it is immortals whom we joke with, work with, marry, snub, and exploit – immortal horrors or everlasting splendors. . . . Next to the Blessed Sacrament itself, your neighbor is the holiest object presented to your senses.

College students naturally have many opportunities to build relationships, whether with peers, professors, RA’s and RD’s, administrators, countless facility workers, or with the wonderful people at MAP and Hicks and the Student Union who prepare our food.

BBQ Dinner at ESC
BBQ Dinner: We cooked for our French friends and invited them to the ESC at the beginning of the semester.

One of the special joys of being in France this semester is having the additional opportunity to build intercultural friendships. Our program is structured to encourage these intercultural relationships, as the American and French students have a weekly class together at ONIRIS, our partner school in Nantes, and then go to dinner together nearby.

This year, the cross-cultural class challenged students to think about the ways cultural differences can be a barrier as well as a stepping stone to advancing intercultural communication. Oftentimes we have projects and discussions in class, allowing us to get to know each other better while learning the course material.

I am definitely a fan of the weekly dinners after class. We order in French, get our food (cafeteria-style), find a table, and eat with our friends. Most of our conversations are in English, though my friends were curious about my progress in French and this week asked me to try saying a few things — and were quite pleased that I could do so, even though I have very limited grammar and vocabulary.

COMM Group Project
Some of our class projects are quite fun.

We also had a Christmas party at the study center and are invited the seventeen French students to come as well. It was such a blast!

Anyone contemplating the program should consider the value of making friends with students from other cultures, as it is something that is highly encouraged. Depending on one’s involvement at our church, it is also possible to get to know students from many other countries as well. The church also hosts an international student’s ministry which serves people from all over Asia, Europe, and Africa.

I’m grateful for the experiences I have had and hope to spend these final weeks valuing friendships even as I finish some big assignments and take final exams.

A Virtual Way Through the Crowd

Crowds are curious things. As I have navigated many in airports, train stations, and other public places in France this semester, I’ve been surprised at how a path through the crowd that my friend took ahead of me, a few seconds ago, is not necessarily the path I should take. People are moving constantly and I need to keep moving as well if I do not want to lose my guide.

Dr. Cory Boatright, Assistant Professor of Computer Science at Grove City College, has done research on crowd simulation since 2011. Crowd simulations are usually of pedestrians, and are defined by giving hundreds or thousands of virtual agents a starting position and a destination. When the simulation starts, individuals begin to make their way through the ever-changing crowd. While visualization is not required, it is helpful for understanding. Below is a screenshot from Dr. Boatright’s work:

From Dr. Boatright's research

While working on his Ph.D., Dr. Boatright’s research focused on using a data-driven approach to crowd simulation, instead of a procedural or geometrical take, with the intent of making the simulation faster. This past summer, two Grove City students worked on updating the framework used for the simulation. When that project is completed, it will be easier to set up simulations to research other things.

“The nifty thing about crowd simulation,” Dr. Boatright noted, “is that it crosses a lot of fields — everything from massively parallel computing to law enforcement.” One interesting application explored in a paper [1] is using software to process a video feed of a crowd, update a live model of the crowd, and predict destinations of pedestrians. The software could then flag unusual behavior, like someone in a lobby who has been wondering about and is not taking a direct path anywhere.

A second research interest for Dr. Boatright is vectorizing raster graphics. A raster image is essentially defined by a grid of pixels, where every pixel has a defined color. Photos, for instance, are raster images. A vector image, on the other hand, uses shapes or paths to define what is seen. Thus a vector image has infinite resolution. Vector graphics are generally used in design, while raster graphics are used for photos.

So when might one want to vectorize a raster image? Boatright referenced Wendell August Forge, which often makes ornaments based on photos provided by customers. This requires an artist to take the photo and trace the important paths in a vector format. If this task could be completed with software, it would save a lot of time.

Boatright has always been interested in large-scale problems and squeezing as much performance as possible out of a computer. Although crowd simulations and IBM’s Watson do very different things, Boatright’s simulation can handle thousands of virtual agents on his personal PC, while Watson fills a room.

Anyone interested in computer science will find that GCC professors, like Dr. Boatright, have a wealth of interesting research to draw on — and some of the research areas present opportunities for students to get involved.
