Mahesh Ramesh

Hello, I'm Mahesh!

M.S. Computer Science, UW–Madison, 2026

I recently completed my M.S. in Computer Science at the University of Wisconsin-Madison. I am currently a Research Scientist Intern at Trata (YC W25), where I work on post-training and evaluation of language-model agents in long-horizon financial environments. In September, I will join the MATS OpenAI Stream.

My research focuses on reinforcement learning and post-training for language models, RL generalization, LLM evaluation, and AI safety.
