    Biography

    Prior to his retirement, Bill Lasher was a professor in the Mechanical Engineering program at Penn State Erie Behrend. He received his B.S.E. and M.S.E. degrees in Naval Architecture and Marine Engineering from the University of Michigan and his Ph.D. in Mechanical Engineering from the State University of New York at Buffalo. He has worked as a yacht designer at C&C Yachts in Oakville, Ontario; as an assistant professor at Gannon University in Erie, PA; and as a computer applications engineer at American Sterilizer Company in Erie, PA. He joined the faculty at Behrend in 1984 and led the transition from a multi-disciplinary engineering program to separate Mechanical and Electrical Engineering programs, and also played a key role in initial accreditation of the ME program in 1994.

    He is a Fellow of the American Society of Mechanical Engineers, as well as a member of the Society of Naval Architects and Marine Engineers, the American Society of Engineering Education, and Tau Beta Pi Engineering Honorary Society. His research interests are in computational fluid dynamics and engineering education. In 2003 he took a sabbatical leave to work with the Yacht Research Unit in Auckland, New Zealand on sail aerodynamics. He taught courses in engineering design, fluid mechanics, strength of materials, and computational fluid dynamics.

    Dr. Lasher was named Editor-in-chief, Society of Naval Architects and Marine Engineers Journal of Sailboat Technology, 2008-present.
