About Me
I am a researcher in human-machine learning, at the intersection of robotics, game theory, dynamical systems.
I am completing my PhD at the University of Washington in Seattle, WA.
Research
I am fourtunate to be advised by Prof. Sam Burden and Prof. Lillian Ratliff in the Electrical and Computer Engineering (ECE) department at UW.
Our research focuses on how optimizers interact with each other (and with humans).
We study
multi-agent
decision-making
through the lens of
game theory and
bounded rationality
and
conduct online experiments to validate the theory.
Our theory offers a compelling model for decision-making in continous action spaces when agents learn about each other, and our experiments that were conducted with annonymous participants also provide strong supporting evidence for the theory.
During my time at UW, I also collaborated with the Autonomous Control Laboratory (ACL) on human-machine interfaces and the Computational Neuroscience Center (CNC) community at UW on the co-adaptive interfaces.
My prior research at Harvey Mudd College was in the Lab for Autonomous and Intelligent Robotics (LAIR) on cooperative multi-agent underwater robotics and aerial vehicles, with an emphasis of deploying robot systems in challenging environments such as confined caves and open waters.
In my free time, I enjoy cooking, hiking, and music. I like to build things and dream up projects.
