Barbara (Bella) Hayes-Roth is an American computer scientist and psychologist whose research inartificial intelligence includes work onknowledge acquisition,[A]automated planning and scheduling,[B]spatial cognition,[C] theblackboard system,[D]real-time computing,[E]adaptation,[F] and intelligent behavior ininteractive storytelling.[G] She was a senior research scientist and lecturer in computer science atStanford University 1982–2002.[1] She holds two patents on interactive characters and founded Extempo Systems, Inc.[2]
Hayes-Roth majored inpsychology atBoston University, graduatingmagna cum laude in 1971. She went to theUniversity of Michigan for graduate study in psychology, earning a master's degree in 1973 and completing her Ph.D. in 1974.[1] Her dissertation, Interactions in the Acquisition and Utilization of Structured Knowledge, was supervised byRobert Bjork.[3]
She became a researcher atBell Laboratories from 1974 to 1976, and at theRAND Corporation from 1976 to 1982, also holding a position as consulting assistant professor in psychology at theUniversity of California, Los Angeles. She became a senior research scientist and lecturer at Stanford in 1982.[1]
