I currently work as an Assistant Professor at Bryn Mawr College.

Office: 200B Park Science Center

My current projects focus on analyzing motion from video and building multi-modal characters for video games. I primarily use a mix of experimental (e.g. user studies) and modeling approaches to understand the effect of different design decisions on non-player characters, avatars, and game design.

I completed a B.Sc. in computer science from McGill University. After college, I worked 10 years as a professional software engineer with specialties in networking, graphics, and behavioral modeling. I later completed a masters and PhD degree from the University of Pennsylvania. During my PhD, I studied character and crowd animation, body language, and built a number of game-based experimental platforms. After my PhD, I worked several years as an AI and 3D game programmer, implementing projects for Kythera AI (Moon Collider LLC), Cesium, Monument Lab, and Clemson and New York University. I returned to academics full-time in 2018 and started work at Bryn Mawr in 2020. My research currently is looking at methods for analyzing motion from video, analyzing and creating procedural characters, and game-based learning and experimentation.

Here is my curriculum vitae. If you’d like to learn more about me, I was recently profiled for ACM SIGGRAPH.

Some of my publications are listed below. You can see an up-to-date list on Google Scholar.

Most of my work (research, hobbies and teaching!) is open-source and available on github.
