I am a Research Scientist at Netflix, where I work to push the boundaries of entertainment through AI innovation, particularly in video games. Previously, I received a PhD at MIT advised by Justin Solomon, a B.S. in Computer Science and Mathematics and an M.S. in Mathematics, both at Stanford University.

My research centers on one question: How can we make interaction with AI not just intelligent, but genuinely fun? I believe the key is to use AI to empower player creativity, enabling entirely new forms of AI-assisted expression. To this end, I am exploring the following questions:

Bottom-Up Structural World Modeling. Can we use a bottom-up approach to model a world's logical structure as a compact, text-based formal representation? This format is inherently consistent and it is easy to add interactivity and visual components.

Emergent and Balanced Game Mechanics. Beyond visual assets, can game mechanics themselves, represented as code, be generative, adapting to player input and the world state? Can we enable a true roguelike experience where any player build is viable without unbalancing the game?
