Charles Lessard, Ph.D., Lt. Colonel, U.S. Air Force (Retired), IEEE Life Fellow, Associate Professor, Biomedical Engineering Department, Texas A&M University. Dr. Lessard received his doctorate in Electrical Engineering from Marquette University in 1972, his master's degree in Electrical Engineering from the Air Force Institute of Technology in 1967 and his bachelor's also in Electrical Engineering from Texas A&M University in 1958. As a U.S. Air Force Pilot, he flew F-86L All Weather Interceptors and B-52 Strategic Bombers. He was a Lead Engineer and scientist with the School of Aerospace Medicine and the AF Medical Research Laboratories before serving as the overseas Program Manager and Spain's Field Office director in the installation and testing of Spain's Air Defense system. He joined the Texas A&M Engineering faculty in 1981 as an Assistant Professor after retiring from the Air Force in July 1981. Dr. Lessard has served as an Adjunct Professor with the Air Force Institute of Technology, Electrical Engineering, Assistant Professor, Night Division, San Antonio College, Assistant Professor, Night Division, St. Philips College and Adjunct Professor, Physical Therapy, Texas Women's University. Dr. Lessard specializes in physiological signal processing, design of virtual medical instrumentation, control systems, noninvasive physiological measurements, vital signs, nystagmus, sleep and performance decrement, spatial disorientation, acceleration (G)-induced loss of consciousness (G-LOC), and neural network analysis.
