Biography

Peter A. Lewin, M.Sc., Ph.D. is R.B. Beard Professor of Electrical and Computer Engineering and Biomedical Engineering at Drexel University, Philadelphia. He is also Director of the Ultrasound Research and Education Center in The School of Bioengineering, Bioscience and Health Systems at Drexel University. Dr. Lewin obtained his M.S. degree in Electrical Engineering in 1968 and the Ph.D. in Physical Acoustics in 1979 in Copenhagen, Denmark. Before receiving his Ph.D. degree he was employed by Bruel and Kjaer, Denmark, where he was involved in the development of underwater piezoelectric transducers and associated electronics. From 1978 to 1983 he was associated with the Danish Institute of Biomedical Engineering (now Force Institutes) and The University of Denmark, Copenhagen, where his research activities primarily focused on propagation of ultrasound waves in inhomogeneous media and development of PVDF polymer transducers. In 1983 he joined the faculty of Drexel University. Dr. Lewin was awarded several patents in the field of ultrasound and has authored or co-authored over 200 scientific publications, most of them on topics in ultrasound and is co-editor (with Prof. M. C. Ziskin) of a book Ultrasonic Exposimetry (CRC Press, 1993). His current interests are primarily in the field of biomedical ultrasonics including the design and testing of piezoelectric transducers and sensors, power ultrasonics, ultrasonic exposimetry, tissue characterization using nonlinear acoustics, biological effects of ultrasound, applications of shock waves in medicine and image reconstruction and processing. Dr. Lewin is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) and a Fellow of the Acoustical Society of America. He is also a Fellow of the American Institute of Ultrasound in Medicine (AIUM and served as a Chair (1997-1999) of the AIUM's Technical Standards Committee. In addition, Dr. Lewin is a member of the honorary Society Sigma Xi and serves as a consultant to the U.S. Food and Drug Administration, Center for Devices and Radiological Health. Dr. Lewin is also a chairman of one of the working groups within the International Electrotechnical Commission (IEC), Technical Committee on Ultrasonics. In 2007 he was elected Fellow of the American Institute for Medical and Biological Engineering.
