Biography

Raj Acharya obtained his Ph.D from the Mayo Graduate School of Medicine/University of Minnesota in 1984. Since then, he has worked as a Research Scientist at Mayo Clinic and at GE (Thompson)-CGR in Paris, France. He has also been a Faculty Fellow at the Night Vision Laboratory in Fort Belvoir in Washington D.C. and has been a NASA-ASEE Faculty Fellow at the Johnson Space Center in Houston, Texas. He was the chair of the department of Computer Science and Engineering at SUNY-Buffalo from Fall 1999 till Spring 2001. He is currently the department head of Computer Science and Engineering at the Pennsylvania State University and the director of the Advanced Laboratory for Information Systems & Analysis.

He has been the Chair of Special Sessions in the IEEE International Conference on Multimedia and Expo (July-August, 2000). He is on the editorial board of the International Journal of Computerized Medical Imaging and Graphics. He has been a panel member of the National Institute of Health, BioImaging study section. He was on the scientific board of the IEEE Model Based 3D Biomedical Image Analysis. He was the Session Chair at the 1996 International SPIE Symposium. He was General Chair of 1994 SPIE International Conference on Physiology and Function from Multidimensional Images. He was also Co-Chair of 1994 IEEE Workshop in Biomedical Image Analysis. He was General Chair of SPIE Conference on Biomedical Image Processing (1992 and 1993).

His research work has been featured among others in Businessweek, Mathematics Calendar, The Scientist, Diagnostic Imaging and Biomedical Engineering Newsletter and Drug Discovery.
