Biographical Sketch

Yongjian Yu was born in Chengdu, Sichuan, China, in 1961. He received the B.S. degree in physics, M.S. and Ph.D. degrees in electrical engineering from University of Electronic Science and Technology of China (UESTC), Chengdu, Sichuan, China, in 1982, 1985 and 1989, respectively. He was a member of the faculty of UESTC from 1989 to 1999, where he had held the position of Associate Professor of electronic engineering since 1993. From August 1993 to December1995, he was a Visiting Scholar with the Remote Sensing Group, Alenia Spazio SpA, Rome, Italy. From 1999 to 2000, he was a Research Assistant with the Department of Electrical and Computer Engineering, Oklahoma State University, Stillwater, Oklahoma; From 2000-2003, he was been a Research Assistant with the Department of Electrical and Computer Engineering, University of Virginia, Charlottesville, Virginia. Dr. Yu received the Science and Technology Progress Award of the Ministry of Electronics Industry of China in 1994 and the National Scientific and Technological Progress Award of China in 1999.

Research Interests

Yu's areas of research included medical ultrasound imaging, speckle signal, and speckle image processing systems. Specifically, Yu researched speckle reducing anisotropic diffusion and the detection of contours of organs using normalized first order and second order differential operators.
