Professor Snyder has served on the electrical engineering faculty of Washington University since 1969. He is presently senior Professor of Electrical and Systems Engineering.  He served as Chairman of the Department of Electrical Engineering from 1976 to 1986.  In 1986, he founded the Electronic Systems and Signals Research Laboratory and served as its Director from then until 1997. 

Professor Snyder's research and teaching interests are in the area of quantitative imaging and statistical estimation, with applications in radiology, optics, and radar and infrared imaging. His work with students and collaborators on the development, testing, and implementation of model-based methods for tomographic imaging is yielding images of radionuclide distributions that are more accurate, less noisy, and with improved resolution compared to images produced with more conventional methods.

Professor Snyder has collaborated with researchers in the Department of Radiology to improve X-ray tomographic images of the body in the presence of high density metallic objects used in the treatment of advanced cervical cancer.  His collaboration with faculty in the Department of Earth and Planetary Science was aimed at improving the use and interpretation of hyperspectral image-data acquired with optical sensors operating at visible and infrared wavelengths.  He participated in the development of improved methods for producing images acquired with ground- and space-based telescopes and with microscopes.  In collaboration with astronomers at the Space Telescope Science Institute in Baltimore, he helped develop new approaches for improving images acquired with the Hubble Space Telescope and with high performance electronic cameras in ground-based observations through atmospheric turbulence.

Professor Snyder served as Associate Editor for Random Processes for the IEEE Transactions on Information Theory and was the 1981 President of the IEEE Information Theory Society.  He served as Topical Editor for Signal and Image Processing of the Journal of the Optical Society of America A.
