I am a PhD student in Robotics at University of Michigan, advised by Assistant Professor Bernadette Bucher and working on robot learning for mobile manipulation with explicit hierarchical representations.

Before, I was a M.S. student at Minnesota Robotics Institute advised by Professor Karthik Desingh as part of his Robotics: Perception, and Manipulation Lab. My research interests were in object manipulation for domestic robots, particularly in developing algorithms that enable robots to learn the relationship between multiple objects in cluttered environments from human demonstrations.

I spent the Summer of 2022 working on the Amazon-University of Washington Robot Manipulation Project. Before that, I completed my B.S. in Computer Science and Mathematics at University of Washington. During my B.S., I worked as a research assistant at the UW Robotics and State Estimation Lab.
