About Me

I am a researcher at the US DEVCOM Army Research Lab studying human-guided machine learning. My research focuses on human-in-the-loop learning, sequential decision-making algorithms, and robot learning. I’m excited about the potential for algorithms leveraging human-AI interaction to support people in many personalized ways. Outside of research, I am committed to positively impacting people’s lives through mentorship and outreach.

I completed my PhD in Control and Dynamical Systems at Caltech, where I was fortunate to be advised by Professors Yisong Yue and Joel W. Burdick and to work on optimizing the walking gaits of a robotic exoskeleton. After that, I was a postdoctoral researcher and CI Fellow at UC Berkeley, working with Professor Ken Goldberg in the AUTOLAB. Prior to my current position, I was a postdoctoral fellow at the Army Research Lab, working with Dr. Nicholas Waytowich.
