I am a Computer Science and Engineering Ph.D. student at the University of Washington, where I work with Pedro Domingos. I received my B. Eng. in Computer Engineering from the University of Victoria in British Columbia, Canada.

My current research is on developing tractable models and inference algorithms, particularly with respect to probabilistic inference and nonconvex optimization. Longer term, I am interested in developing general learning techniques for artificial intelligence that are domain agnostic and rely on fewer assumptions than modern methods.

In previous work, I have explored nonparametric Bayesian modeling, planning and decision making, reinforcement learning, imitation, and goal inference. I've had the pleasure of being advised by both Rajesh Rao and David Wingate, and have had the good fortune to visit other research labs, including MIT in the labs of Leslie Kaelbling and Josh Tenenbaum, Berkeley with Tom Griffiths in the Computational Cognitive Science Lab, and an internship at Intel Labs in Seattle, working with Dieter Fox on Human Robot Interaction.

Here is a link to my CV.
