About
I am currently the Roger Dashen member at the school of Natural Sciences at the Institute for Advanced Study (IAS) in Princeton. I previously served as a Junior Fellow at the Harvard Society of Fellows, and as a BHI Fellow at Harvard University Black Hole Initiative and at the Center for the Fundamental Laws of Nature.
I am interested in diverse aspects of high-energy physics, astrophysics and quantum gravity. During my PhD I studied how Scattering Amplitudes, one of the signature objects in Quantum Field Theory, can be used to understand both classical and quantum aspects of gravity.
I am currently pursuing research related to black hole physics, broadly understood. This involves tools from S-Matrix theory, celestial holography, quantum information and machine learning, among others.
