Allen Robert Tannenbaum (born January 25, 1953) is an American/Israeli applied mathematician and presently Goodrich Professor of Electrical and Computer Engineering at the University of Alabama, Birmingham. He received his Ph.D. with thesis advisor Heisuke Hironaka at the Harvard University in 1976.

His has performed 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 problem using techniques from Nevanlinna-Pick interpolation theory, which was one of the first H-infinity type problems solved. He also pioneered the use of partial differential equations in computer vision and biomedical imaging co-inventing with Guillermo Sapiro an affine invariant heat equation for image enhancement. His work has won a number of awards including IEEE Fellow in 2008, O. Hugo Schuck Award in 2007 (shared with S. Dambreville and Y. Rathi), and the George Taylor Research Award from the University of Minnesota in 1997. He is also well known as the one of the authors of the textbook Feedback Control Theory (with John Doyle and Bruce Francis), which is currently the standard introduction to robust control at the graduate level.
