Watson Research Center; ETH, Zurich; University of Sao Paulo, Brazil; Oak Ridge National Lab.; Australian National University, Canberra; Chuo University, Tokyo; Monash University, Melbourne, Australia; and IIT/Kharagpur.

A Fellow of IEEE, a Fellow of the ACM, and Fellow of the ICA, Dr. Deo has authored four books in computer science (which have been translated into several languages, including Russian, Polish, and Japanese) and over 200 refereed research papers. He holds a number of patents in computer hardware and is a recipient of NASA's Apollo Achievement Award. Among his other awards are: Gold Medal of Patna University; Drake Scholar at Cal Tech; Governor's Award for Outstanding Contribution to High Tech Research in Florida (1989); UCF's Distinguished Researcher Award-89; UCF's Professorial Excellence Program Award (1997); UCF's Teaching Incentive Program Award (1999); and UCF's Excellence in Graduate Teaching Award (2001). He has served as an editor/guest editor for various journals--including the IEEE Trans. on Circuits & Systems and the Journal for Parallel and Distributed Computing. At present he is on the Editorial Boards for The Journal of Supercomputing, and the VLSI Design. He is currently the President of the Forum for Interdisciplinary Mathematics (http://www.eecs.ucf.edu/fim) His research interests include parallel algorithms and parallel data structures, network optimization algorithms, combinatorial computing, complex networks, and graph theory.
