About

Hi, I'm Dylan! I'm a fourth year PhD student in the Machine Learning Department at CMU, where I am fortunate to be advised by Zico Kolter. My work is supported by a NSF Graduate Research Fellowship.

My research focuses on making large frontier models behave in safe, controllable, and predictible ways. Currently, this involves training safe language models and curating better training data. This has also involved understanding their behavior and generalization, and improving their interactions with weak supervision or domain knowledge.

Before, I studied math and computer science at Brown University, where I was advised by Stephen Bach. In the past, I served as a student researcher at Google Research, and a research intern at Amazon AWS, the Bosch Center for AI, and NASA JPL. If you are interested in my work, feel free to get in touch. I am always looking to chat about research and form new collaborations!
