About Me

Working on something new.

Previously I was a research scientist at Biohub and Springtail.ai. Before that, I graduated from the University of Chicago with degrees in Computational Applied Math, Statistics, and Economics. I also worked on reinforcement learning at the Toyota Technical Institute at Chicago.

I like to share research insights on my blog and occasionally post on X.
