I am a fifth-year Ph.D. candidate in Computer Science & Engineering at the University of Michigan, advised by Professor Michael P. Wellman in the Strategic Reasoning Group. My research interests lie at the intersection of artificial intelligence and algorithmic game theory. I am also passionate about teaching, mentorship, and working to increase diversity within CS.

Research
I develop methods to study multi-agent strategic interactions using empirical game-theoretic analysis, focusing on learning game models from data, designing algorithms to analyze large games, and applying these techniques to mechanism design.
Keywords: empirical game-theoretic analysis · simulation-based games · game-model learning · empirical mechanism design · multi-agent systems
Teaching
I have served as a primary instructor, graduate student instructor, and undergraduate teaching assistant across a range of CS courses. In 2025, I was honored to receive the Rackham Outstanding Graduate Student Instructor Award (1 of 20 selected university-wide from ~2,000 GSIs).

Asking questions. Favorite icebreaker: if from here on out you could only age from the neck up or from the shoulders down, which would you pick, and why?
Black olives on pizza. I will defend this.
Making spreadsheets. If I'm thinking about it, there's probably a spreadsheet for it.
Popcorn. My brother gave me a dedicated popcorn bowl in high school, and I still use it.
Things I'm not into:
Eating vegetables.
