Hi, my name is Wayne. I am a third year Ph.D. Student in the Computer Science Department at CMU advised by Chris Donahue and Ameet Talwalkar. I am funded by the 2025 NDSEG Fellowship.

I work on applications of machine learning that support human creativity with a focus on game development. My work includes human-centric code evaluation (1, 2) and agentic game development (3). I have also worked on music (4, 5), healthcare, and space automation (6, 7).

I completed my undergraduate and master’s at the University of Southern California. Before starting my Ph.D., I spent around 7 years in industry working as an Applied Scientist at AWS (2019-2023) and NASA’s Jet Propulsion Laboratory (2016-2019). If you are interested in any of my research topics or considering a Ph.D. after industry feel free to reach out.
