Hey, I'm Apoorv! I'm a third-year CS PhD student at Brown, where I'm very fortunate to be advised by Chen Sun & Ellie Pavlick. I am supported by Brown's Presidential Fellowship. My current research interests are in modularity & compositionality in language models. My prior interests are illustrated by the works below! I have also had the great pleasure of working at the Allen Institute for AI and with Noah Snavely & Hadar Averbuch-Elor as an undergrad at Cornell.
