Hi, I am a fifthyear PhD student in mathematics at Columbia University. My advisor is Ivan Corwin and my main research interests include probability theory and integrable systems.
During fall 2021, I participated in the "Universality and Integrability in Random Matrix Theory and Interacting Particle Systems" program at the Mathematical Science Research Institute as a Vitulli program associate fellow.
Before Columbia, I was an undergraduate student at Williams College and my senior thesis advisor was Susan Loepp.
