I am an Applied Scientist at Amazon Alexa AI. I work on Alexa’s language understanding engine and my research interests include semantic parsing and speech/conversational AI. I got my PhD in Computer Science from UMass Amherst in 2022. I worked with Prof. Andrew McCallum in the Information Extraction and Synthesis (IESL) Lab and my dissertation focused on improving low resource language understanding in voice assistants.
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.
