I recently completed my PhD in Computer Science and Engineering at the University of Washington, advised by Pedro Domingos.

My current research is on developing highly-expressive but tractable machine learning models and algorithms in order to build more intelligent systems and tools. Applications include deep learning, probabilistic modeling, computer vision, nonconvex optimization, and protein folding.

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 and my github.
