About Me

Welcome to my academic website. I am a Ph.D. student at UCSD working primarily in Philosophy of Science and Epistemology. Most of my projects can be captured by the catchphrase "formal tools for social phenomena." My research is largely split into two streams, one of which focuses on epistemic communities and their interactions with machine learning (ML) systems, while the other is a more traditional approach to the philosophy of science with a focus on the role of algorithmic tools in scientific theorizing. I primarily use methods from probability theory and agent-based modeling to explore group social dynamics and reasoning under risk. Much of my work is aimed at advocating for modeling and simulation as philosophical methods. Prior to philosophy, I did research in computational geography, using deep neural networks (DNNs) to explore environmental and social impacts on communities.
