RESEARCH
I am a physicist seeking ways to understand generalization in deep learning. Towards this goal, I study AI as a scientific discipline, where both empirical validity and explainable methodologies are essential. For instance, see [here] for our work on generalization and optimization in physics-informed neural networks, and see [here] for our work on double descent and online/offline correspondence in similarity learning.
Previously, I explored the construction of models to explain small- and large-scale phenomena in the universe. I worked on the interplay between particle physics and cosmology, learning from the early universe how to build and interpret our models of particle physics. See [here] for all publications.

ABOUT ME
I'm a Research Fellow at Oxford Theoretical Physics exploring the interplay between Machine Learning and Physics. I'm hosted at Ard Louis group. Before Oxford, I worked as a Research Scientist at IBM Research UK. Previously, I was at ICTP in Trieste, DESY Theory Group in Hamburg, CTP at MIT, University of São Paulo, and University of Campinas. For more details, please see my [CV].
