Introduction to Biomedical Engineering

Douglas A. Christensen received the B.S.E.E. degree from Brigham Young University, Provo, UT, in 1962, the M.S. degree from Stanford University, Stanford, CA, in 1963, and the Ph.D. degree from the University of Utah, Salt Lake City, in 1967. From 1972 to 1974, he held a special National Institute of Health (NIH) Postdoctorate position in biomedical engineering at the University of Washington, Seattle. He has been a Faculty Member at the University of Utah since 1971. He currently holds a joint appointment as Professor of bioengineering and Professor of electrical engineering. He is the author of Ultrasonic Bioinstrumentation (New York: Wiley, 1988) and coauthored Basic Introduction to Bioelectromagnetics (Boca Raton, FL: CRC, 1999).A His major research interests are in the area of waves in biological sensing, including optical biosensors, fluorescent waveguiding immunosensors, numerical modeling of optical waveguides and near-field optical effects, and ultrasonic bioinstrumentation.
