Biography

I am a fifth year graduate student at CICS, UMass Amherst. I work with Prof. Andrew McCallum in the Information Extraction and Synthesis (IESL) Lab. I focus on speech and conversational AI, specifically, improving low resource language understanding in voice assistants. This work is in collaboration with scientists at Amazon Alexa AI, where I interned the past three summers.

Prior to this, I worked with Prof. Hong Yu on safe and interpretable machine learning in healthcare. When I’m not working on research, I’m mostly playing on my PS5 or cheering for India in cricket. I also enjoy tennis and cooking with my wonderful and brilliant wife Emily First.
