Technical Director, Artificial Intelligence Center
Melinda Gervasio, Ph.D., is a Technical Director in SRI’s Artificial Intelligence Center. She focuses on developing technology that combines human and machine intelligence.
Gervasio’s research interests include intelligent assistants, machine learning for autonomous agents, adaptive personalization, interactive machine learning, end-user programming, and intelligent training systems. As the technical lead on a number of government-funded projects, she has developed technologies for learning from demonstration, adaptive assistance, proactive decision support, and recommendation for informal learning.
Before joining SRI, Gervasio co-founded MindShadow, where she played a key technical role in developing a software platform for personalized, content-based recommendation. She was also a research scientist at the Institute for the Study of Learning and Expertise, where she worked on adaptive personalization.
Gervasio has a Ph.D. in computer science from the University of Illinois at Urbana-Champaign and a B.S. in computer science from the University of the Philippines Diliman.
