Profile Picture

Hi! I’m a third year Computer Science Ph.D. student at Columbia University, advised by Dr. Lydia Chilton. My research focuses on human-AI collaboration in creative work and software development. I build interactive tools and explore how people understand, evaluate, and guide AI in their work.

Recently, I interned at Adobe Research, where I worked on disclosure and provenance in AI-assisted image editing. Before Columbia, I worked at Microsoft in New York City.

I hold an M.S. from Columbia, and a B.S. in Computer Science and B.A. in Economics from the University of Chicago, where I worked with Dr. Marshini Chetty and Dr. Sarah Sebo.

I’m looking for research internships for summer 2027 and would love to collaborate on projects around human-AI interaction, creativity support, or developer tools. Please reach out!

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