Chenfeng (Jesse) Gao

I am a PhD student in Technology and Social Behavior at Northwestern University, advised by Prof. Karan Ahuja in the Sensing, Perception, Interactive Computing and Experiences (SPICE) Lab. Previously, I earned an M.S. in Computer Science at the University of Chicago, an M.Des. in Human-Computer Interaction from the IIT Institute of Design, and a B.S. in Mathematics from Renmin University of China. I am a recipient of the Red Dot Design Award, a Best Paper Honorable Mention, and a Best Demo Honorable Mention at ACM CHI 2025.

My research draws on my background in spatial AI, machine learning and sensing, and interaction design to tackle challenging research problems in high-impact application areas: user digitization, context-aware AR experiences, and creativity support tools. My work has been showcased through invited technical demos at Qualcomm, Meta Reality Labs, and Rivet, and covered by New Scientist, The Engineer, and Northwestern Engineering News.

That earlier side of my work lives in my design portfolio.
