I am a PhD Candidate in the Department of Computer Science at the University of Oxford, where I conduct research on probabilistic machine learning with Yarin Gal and Yee Whye Teh. The goal of my research is to develop methods and theoretical insights that enable the safe deployment of machine learning systems in safety-critical settings by drawing on tools from variational Bayesian inference and reinforcement learning. I am particularly interested in Bayesian uncertainty quantification in deep learning, probabilistic inference in reinforcement learning and control, and AI safety.
For my work on safe decision-making under uncertainty, I received the 2021 Qualcomm Innovation Fellowship. I deeply care about equitable access to education and serve as an Equality, Diversity & Inclusion Fellow at the University of Oxford.
I am also an AI Fellow at Georgetown University's Center for Security and Emerging Technology and a Rhodes Scholar.
I obtained an undergraduate degree in mathematics and economics from Yale University, where I received the Charles E. Clark Memorial Award for Academic Excellence and was fortunate to be advised by Sekhar Tatikonda. Subsequently, I earned a master's degree in statistics from the University of Oxford, where I was supervised by Dino Sejdinovic. Prior to my PhD, I conducted research on game theoretic equilibria in digital goods markets, systemic risk in financial markets, and drivers of financial crises. I am a member of the Oxford Center for Doctoral Training in Autonomous Intelligent Machines & Systems (AIMS) and the OECD Network of Experts, as well as a Fellow of the German Academic Scholarship Foundation.
