Bonnie J. Dunbar - Early Life

Early Life

Dunbar was born March 3, 1949, in Sunnyside, Washington. In 1967, she graduated from Sunnyside High School, Sunnyside, Washington. Following graduation in 1971 from the University of Washington, Dunbar worked for Boeing Computer Services for two years as a systems analyst. From 1973 to 1975, she conducted research for her master's thesis in the field of mechanisms and kinetics of ionic diffusion in sodium beta-alumina. She is a member of Kappa Delta Sorority.

In 1975, she was invited to participate in research at the Atomic Energy Research Establishment, Harwell near Oxford, England, as a visiting scientist. Her work there involved the wetting behavior of liquids on solid substrates. Following her work in England, she accepted a senior research engineer position with Rockwell International Space Division in Downey, California. Her responsibilities there included developing equipment and processes for the manufacture of the Space Shuttle thermal protection system in Palmdale, California. She also represented Rockwell International as a member of the Dr. Kraft Ehricke evaluation committee on prospective space industrialization concepts. Dunbar completed her doctorate at the University of Houston in Houston, Texas. Her multi-disciplinary dissertation (materials science and physiology) involved evaluating the effects of simulated space flight on bone strength and fracture toughness. These results were correlated to alterations in hormonal and metabolic activity. Dr. Dunbar has served as an adjunct assistant professor in Mechanical Engineering at the University of Houston.

Dunbar is a private pilot with over 200 hours in single engine land aircraft, has logged more than 700 hours flying time in T-38 jets as a back-seater, and has over 100 hours as co-pilot in a Cessna Citation jet. She was married to fellow astronaut Ronald M. Sega.
