About Me

Hi! I’m a PhD student at the University of Massachusetts Amherst NLP Lab, advised by Prof. Mohit Iyyer with a research focus on natural language processing (NLP). My past work is mainly about evaluating and improving the coherence of model-generated text in both short-form and long-form settings, and my current interest lies in LLM watermarking and detection. Before starting my PhD, I finished my undergraduate studies at Smith College with a major in Computer Science and a minor in Mathematics. I’ve also worked as a Software Engineer intern at Amazon.

I like gaming and tinkering with mechanical keyboards in the free time I aggregate from my fluctuating work-life balance (it’s a work in progress ┐(‘～` )┌).
