About Me
Hi, I’m Trenton! I am a 4th year EECS PhD Candidate at the University of Michigan AI lab, advised by Jenna Wiens. During Summer 2024, I was on internship at Microsoft Research Redmond with the Augmented Reasoning & Learning Group mentored by Adith Swaminathan and Tobias Schnabel.
I work on aligning machine learning model behaviors towards high-level principles such as fairness, controllability, and robustness to gaming. I often take inspiration from health/bioinformatics and policy use cases. My work has intersected with areas including ML fairness, strategic classification, causal inference, and LLM evaluation.
I earned my M.S. in Computer Science from Stanford in 2021, and my B.A. in American Studies from Stanford in 2020. I’ve previously worked on video machine learning robustness with HazyResearch and open-domain conversational AI for the Alexa Grand Prize Socialbot Challenge with the Stanford NLP Group. I was also a contributor to the Google BIG-bench language model benchmark.
Contact. If you’re another researcher in the machine learning, causal inference, or healthcare space–please reach out if you want to chat about research!
For current Michigan students interested in working with me, please email me to set up a one-off coffee chat if you’d like to discuss some research ideas.
