Profile Picture

Hi! I am a second year Computer Science Ph.D. student at Columbia University, advised by Dr. Lydia Chilton. My research focuses on Human-AI Interaction and Agentic Systems.

I examine how people collaborate with AI systems and agents – from how people learn and adapt to AI tools to agentic methods that improve AI transparency and human intent-alignment.

Prior to joining Columbia, I worked at Microsoft as a CSAM in the Financial Services Industry in New York City. I hold a B.S. in Computer Science and B.A. in Economics from the University of Chicago, where I was advised by Dr. Marshini Chetty and Dr. Sarah Sebo.

I am grateful to be supported by the NSF Graduate Research Fellowship.
