Biography

I am an applied scientist II at Amazon Alexa AI. I work on overcoming imbalanced and scarce real-world data for large language model based conversational AI. Throughout my research, I have studied various kinds of topics to help AI deal with real-world problems. Specifically, I am interested in advancing AI to better serve people, such as in recommender systems or AI assistants that became more than essential in everyday life.
