# Barbara Hayes-Roth

Barbara (Bella) Hayes-Roth is an American computer scientist and psychologist whose research in artificial intelligence includes work on knowledge acquisition, automated planning and scheduling, spatial cognition, the blackboard system, real-time computing, adaptation, and intelligent behavior in interactive storytelling. She was a senior research scientist and lecturer in computer science at Stanford University 1982-2002.

## Education and career

Hayes-Roth majored in psychology at Boston University, graduating magna cum laude in 1971. She went to the University of Michigan for graduate study in psychology, earning a master's degree in 1973 and completing her Ph.D. in 1974. Her dissertation, Interactions in the Acquisition and Utilization of Structured Knowledge, was supervised by Robert Bjork.
She became a researcher at Bell Laboratories from 1974 to 1976, and at the RAND Corporation from 1976 to 1982, also holding a position as consulting assistant professor in psychology at the University of California, Los Angeles. She became a senior research scientist and lecturer at Stanford in 1982.

## Fiction writing

In addition to her many publications as a computer science researcher, Hayes-Roth is working on a fiction novel, The Ravishing Monica B. Reddy. An excerpt from the novel, Devesh Reddy, D-Day, was published in a 2020 issue of Chicago Quarterly Review. The novel is set in early 21st century Silicon Valley.
