Biography
Prof. Clymer received the B.S.E.E. and M. S. degrees in electrical engineering from The Ohio State University in 1981 and 1982, respectively, and the Ph. D. degree in electrical engineering from Stanford University in 1987. From 1981 to 1983 he worked in the Advanced Subsystems Department of Hughes Aircraft Company Space and Communications Group in El Segundo, California. He has been on the faculty of Electrical & Computer Engineering at OSU since 1987. He has been Participating Faculty (1991-2005) and Core Faculty (2005-present) in Biomedical Engineering at OSU, and has held a faculty appointment in the Department of Biomedical Informatics at OSU since 2002.
Prof. Clymer has worked as a consultant for the past 10 years for The
Cleveland Clinic Foundation, Cleveland, Ohio, on adaptive image processing of
xray images, 3D reconstruction of transesophageal ultrasound images of cardiac
valves, 3D reconstruction of mammograms, feasibility of MRI for imaging aortic
atherosclerotic plaques and classification of atherosclerotic plaques from
texture analysis of intravascular ultrasound (IVUS) images of coronary
arteries, signal analysis and data fusion (EEG, EKG, EMG, etc.) for overnight
sleep studies, cone beam reconstruction for a x-ray computed tomographic
microscope, and image texture analysis of trabecular structures for assessment
of osteoporosis and prediction of fracture. He has an Adjunct Staff appointment
in the Department of Biomedical Engineering at The Cleveland Clinic Foundation.
Dr. Clymer is a senior member of IEEE.
Research Interests
Dr. Clymer's current research activities are processing and capture of medical images, including MRI, mammography, ultrasound and x-ray computed tomographic microscopy; signal processing of EEG, ECG and phonocardiographs; adaptive filtering; signal processing to simulate human perception of audio for synchronization of movement for a biped robot; and Fourier transforms and linear systems.
Courses Taught
Prof. Clymer has taught a wide range of courses, including ECE 706 Medical Imaging, which runs every spring quarter. He also occasionally teaches ECE 205 and ECE 301, (basic circuits sequence), ECE 351, ECE 352 (linear systems sequence), and ECE 732 (laser electronics).
