(interactive) Machine Learning | Audio Signal Processing | HCI

I am currently an AI reseacher in AI Lab of 3M. I completed my PhD in computer science at Northwestern University as a member of the Interactive Audio Lab (Advisor: Bryan Pardo).

My research interests inlucde machine learning, audio signal processing (e.g., sound event recognition), intelligent interactive system, multimedia information retrieval, and human-in-the-loop interface. I also enjoy working on a musical interface and interactive media art.
