David is an associate professor at the University of San Francisco. His research interests are natural language processing, machine learning, and databases — specifically on the personal and cultural/demographic information transmitted during speech and typing. This research may lead to more accurate speech recognition systems.

Prior to joining USF, David was a research assistant in the Speech Lab at Queens College and an instructor at Hunter College. He has previously worked for the City of New York, IBM, United HealthCare, and other public and private institutions. David holds a PhD in computer science from the Graduate Center, City University of New York (CUNY).
