Dr. Sheila Widnall, Professor of Aeronautics and Astronautics and Engineering Systems. Massachusetts Institute of Technology (MIT), Cambridge. She has served as Associate Provost, MIT, and as Secretary of the Air Force. As Secretary of the Air Force, Dr. Widnall was responsible for all affairs of the Department of the Air Force. Dr. Widnall was also responsible for research and development and other activities prescribed by the President or the Secretary of Defense.

Since returning to MIT, she has been active in the Lean Aerospace Initiative, with special emphasis on the space and policy focus teams. Her research activities in fluid dynamics have included the following: boundary layer stability, unsteady hydrodynamic loads on fully wetted and supercavitating hydrofoils of finite span, unsteady lifting-surface theory, unsteady air forces on oscillating cylinders in subsonic and supersonic flow, unsteady leading-edge vortex separation from slender delta wings, tip-vortex aerodynamics, helicopter noise, aerodynamics of high-speed ground transportation vehicles, vortex stability, aircraft-wake studies, turbulence, and transition.
