Tristan Saidi

I am a first year PhD student at Columbia University in the department of Computer Science. I'm currently conducting research in Professor Matei Ciocarlie's Robotic Manipulation and Mobility (ROAM) Lab.

I primarily work on robot learning for dexterous manipulation, and have spent some time working on reinforcement learning for snake locomotion as well. Prior to my time with robotics, I spent a year doing research for Professor Kenneth Shepard in the Bioelectronic Systems Lab.

Research

I am interested in exploring the intersection between data geometry and machine learning. Concretely, I want to understand the extent to which data geometry can aid the design and implementation of modern machine learning models.
