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, my research interests include 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!
