James J. Kim

MS in CS @ Cornell University

I’m a MS student in Computer Science at Cornell, broadly interested in automating and accelerating scientific discovery. I’m fortunate to work with Jennifer Sun.

In a previous life, I developed computational models of brain-behavior dynamics in substance use addiction with Amy Kuceyeski in the CoCo Lab, and worked on real-time acoustic sensing for hand pose tracking in wearable tech with Cheng Zhang in the SciFi Lab.

Happy to chat.
