David Woodroffe Allen, Director, Officer and Principal Engineer at Propulsor Technology, Inc., has been recognized by Marquis Who’s Who Top Executives for dedication, achievements, and leadership in engineering.
Drawing upon more than five decades of practiced industry experience, Mr. Allen is an esteemed engineer and executive who has been serving Propulsor Technology, Inc., in Pittsburgh, PA, as director, officer and principal engineer since 1996. He commenced his career with Westinghouse Electric Corporation in Sharon, PA, holding the initial title of associate engineer from 1967 to 1970. Thereafter, he ascended the ranks to engineer for nine years, senior engineer for five years, senior computer scientist for six years, and principal engineer for four years. He concluded his tenure with Westinghouse in 1996 after serving two years as a fellow engineer.
A contributor of myriad articles to professional journals, Mr. Allen holds a Bachelor of Arts from Grinnell College and Master of Science from the University of Pittsburgh. Throughout his career, he has conducted research in current transformer transient performance, magnetic and electric field computation and analysis, computer-aided geometric design, computer vision, and smoothing and curvature analysis of triangle meshes. As such, in an effort to remain abreast of developments within the engineering industry, he is a lifetime member of the Institute of Electrical and Electronic Engineers, where he previously served as section secretary treasurer, and the Association for Computing Machinery.
As a testament to his success, Mr. Allen has garnered multiple accolades. Westinghouse Electric Corporation honored him with the George Westinghouse Signature Award of Excellence in 1989 and 1992, as well as the George Westinghouse Innovation Award in 1993. Most recently, he received the James S. Cogswell Award for Outstanding Industrial Security Achievement in 1998. He has been highlighted in several editions of Who’s Who in Finance and Business, Who’s Who in Finance and Industry, Who’s Who in America, Who’s Who in Science and Engineering, Who’s Who in the East and Who’s Who in the World.
