I am a fifth year graduate student at Princeton University, advised by Assaf Naor. I'm interested in (matrix) inequalities and what they tell us about geometry of Banach spaces. Currently I'm investigating tracial joint spectral measures, a theory I discovered recently. As of Fall 2023, I am in the job market for postdoctoral positions.
