Biography

RESEARCH INTERESTS:

*Multidimensional statistical signal and image processing
*Detection and estimation
*Geometric modeling and estimation
*Bio-medical signal and image processing
*Compressed Sensing and Sparsity

CURRENT FOCUS:

My research focus is on multidimensional signal processing in the presence of uncertainty, the robust extraction of information from diverse data sources, and decision making in the face of noise.

William Clem Karl received the Ph.D. degree in electrical engineering and computer science from the Massachusetts Institute of Technology, Cambridge, in 1991, where he also received the S.M., E.E., and S.B. degrees. He was a Staff Research Scientist with the Brown-Harvard-M.I.T. Center for Intelligent Control Systems and the M.I.T. Laboratory for Information and Decision Systems, from 1992 to 1994. He joined the faculty of Boston University in 1995, where he is currently an Associate Professor of electrical and computer engineering. Since January 1996, he has held a joint appointment in the Department of Biomedical Engineering, Boston University. His research interests are in the areas of multidimensional and multiscale signal and image processing, geometric estimation, detection, and medical signal and image processing. Prof. Karl has been an Associate Editor of the IEEE TRANSACTIONSON IMAGE PROCESSING. He has also served in various organizational capacities, including Session Organizer and Chair for the 36th Asilomar Conference on Signals, Systems, and Computers, Special Session on Inverse Problems in Imaging, Session Organizer and Chair for the 2000 Conference in Information Sciences and Systems Special Session on Medical Imaging, and was part of the Organizing Committee for the 1st SIAM Conference on the Life Sciences. He is a member of Sigma Xi.
