I am a PhD candidate at Stanford Linguistics. I work on semantics, nlp, logic, and cognitive psychology. My dissertation committee is: Christopher Potts (chair), Cleo Condoravdi (chair), and Thomas Icard.

In my semantics work, I build symbolic models for discourse particles, clause-types, modals, and conditionals. In nlp, I work on compositional generalization and interpretability. As an undergrad, I read Philosophy.

With Cleo Condoravdi, I co-organize the Construction of Meaning workshop. With Jasper Jian, I co-organize a group at the intersection of language modeling and linguistic theory.

Goings on:

Mar 2026: New paper Mirativity on the Table (co-author: Veda Kanamarlapudi) now out.

Mar 2026: For the Spring Quarter, I am a TA for LINGUIST 130A: Intro to Semantics & Pragmatics.

Dec 2025: I successfully defended my dissertation proposal.

Nov 2025: I presented Distinguishing fair from unfair compositional generalization tasks (co-authors: Christopher Potts and Cleo Condoravdi) at EMNLP 2025.

Mar 2025: I presented my work on the semantics of conditional rhetorical questions at Berkeley Syntax and Semantics Circle. Slides available here.

Misc:

I have designed and taught formal logic courses at UConn (CT, USA) and LUMS (Lahore, PK). Another tidbit: I am trained in Hindustani classical music (vocals). My favorite raags are Kedar and Yaman.
