I am a PhD Candidate in the Department of Computer Science at Oregon State University. My primary research interests are Computer Vision and Artificial Intelligence, and my thesis work involves designing algorithms to understand American football in video. My advisor is Alan Fern. I’m also working with Ron Metoyer on methods for visualizing the diversity of multivariate data sets and Paul Paulson on integrating Linux kernel development into the operating systems curriculum here at OSU.

In my spare time, I work with the Coalition of Graduate Employees, AFT Local 6069, which is the union that represents graduate teaching and research assistants at OSU. If I have time left over after that (which is seldom), I like brewing beer, and reading books, and appreciating baseball. I also sometimes pretend I know something about photography.

You can explore my work on this website.

Here’s a news story about the DSP that ran on KVAL CBS 13 (the title is theirs, not mine): Move over, RoboDuck: Beaver football bot ‘sees’ plays – and learns.

And, here’s a story that ran on KEZI 9 ABC News: OSU Scientists Develop Computers that “Watch and Learn”.

My advisor, Alan Fern, was also interviewed about our work on NW Sports Night with Ron Callan on KPAM-AM 860, The Voice of Portland.  You can listen to the piece about our work starting around the 21:45 mark of that link.

There also were several other stories, including the ones below:

• Corvallis Gazzette Times: Beavers football tapes used in artificial intelligence research at OSU
• Science 2.0: Artificial Intelligence Gets Some Help From Football Players

Update: The source code for the demo I gave during the OSSC is available here:

• siftDemo.c

You need a webcam to run it.  All you have to do is compile it with my SIFT library, put your own target (the thing you want to find in the webcam’s video stream) and overlay (the thing you want to replace the target in the webcam’s video stream) images at ./target.jpg and ./overlay.jpg, and execute.  Press <space> to outline the detected target and ‘a’ to place the overlay image on top of it.  Should run in real time if you’ve got a reasonable enough processor.

Here are some screenshots of it in action:

SIFT Matches and the target detected in the webcam stream.

MAGIC! Overlay image placed in the webcam stream.
