Research
I am generally interested in techniques that combine machine learning and engineering. Within robotics, I am particularly
interested in ill-defined engineering and autonomy challenges. Often, these problems require some "human intuition" to help
constrain the solution. Some techniques I have been investigating involve learning from demonstration (LfD) and Inverse Reinforcement Learning (IRL).

Terrain traversability in off-road autonomy has traditionally relied on semantic classification or resource-intensive dynamics models to capture vehicle-terrain interactions. However, our experiences in the development of a high-speed off-road platform have revealed several critical challenges that are not adequately addressed by current methods at our operating speeds of 7—10 m/s.

Since beginning my PhD, I have been primarily focused on work related to the DARPA RACER program as part of the UW team. The robot itself is a modified Polaris RZR with onboard sensing and compute. My work on the team has consisted of a range of jobs:

In an undergraduate project, I tackled part of the challenge of teaching robots to perform motor skills from a small number of demonstrations. We proposed a novel approach by joining the theories of Koopman Operators and Dynamic Movement Primitives to Learning from Demonstration. Our approach, named Autoencoder Dynamic Mode Decomposition
