Who is Allen Tannenbaum?

Allen Robert Tannenbaum is an American/Israeli applied mathematician and presently Professor of Computer Science and Applied Mathematics at the State University of New York at Stony Brook. He has held a number of other positions in the United States, Israel, and Canada including the Bunn Professorship of Electrical and Computer Engineering and Interim Chair, and Senior Scientist at the Comprehensive Cancer Center at the University of Alabama, Birmingham. He received his Ph.D. with thesis advisor Heisuke Hironaka at the Harvard University in 1976.

Tannenbaum has done research in numerous areas including robust control, computer vision, and biomedical imaging, having more than 450 publications. He pioneered the field of robust control with the solution of the gain margin and phase margin problems using techniques from Nevanlinna–Pick interpolation theory, which was the first H-infinity type control problem solved. Tannenbaum used techniques from elliptic curves to show that the reachability does not imply pole assignability for systems defined over polynomial rings in two or more variables over an arbitrary field.
