About


Hi! I am a computer science and honors math major at the University of Michigan. I am currently most interested in reinforcement learning research and work with Prof. Lei Ying and Prof. Gabriel Poesia. Specifically, I am most interesting in solving problems relating to RLHF, Deep RL, and Sample Efficient RL. You can view my papers here.


I also work as the Head Instructional Aide for the Advanced Topics Section of EECS 203 Discrete Math and as a Grader for ECE 567 Reinforcement Learning Theory at UM.


Take a look at my blog where I write about math/cs/ai/ml things that interest me. Also check out my tech stack including my config/dotfiles for my NixOS/Hyprland setup. Or you can view my sci-fi reading list.


If you'd like to chat, please reach out to me at ude [tod] hcimu [ta] sumssae!
