Kalyan Perumalla, Ph.D., is a Distinguished R&D staff member and manager in the Computational Sciences and Engineering Division at the Oak Ridge National Laboratory, and an adjunct professor in the School of Computational Sciences and Engineering at the Georgia Institute of Technology. Dr. Perumalla founded and currently leads the Discrete Computing Systems Group at the Oak Ridge National Laboratory. He earned his Ph.D. in Computer Science from the Georgia Institute of Technology in 1999. His areas of interest include reversible computing, high performance computing, parallel discrete event simulation, and parallel combinatorial optimization.
Dr. Perumalla is a winner of the prestigious US Department of Energy Career Award in Advanced Scientific Computing Research, 2010-2015.

His primary research contributions are in the application of reversible computation to high performance computing and in advancing the vision of a new class of supercomputing applications using real-time, parallel discrete event simulations.

His recent book Introduction to Reversible Computing is among the first few in its area. He co-authored another book, three book chapters, and over 100 articles in peer-reviewed conferences and journals. Five of his co-authored papers received the best paper awards, in 1999, 2002, 2005, 2008, and 2014, and two were finalists in 2010.
Dr. Perumalla serves as program committee member and reviewer for several international conferences and journals. He is a member of the editorial boards of the ACM Transactions on Modeling and Computer Simulation (TOMACS) and the SCS Transactions of the Society for Modeling and Simulation International (SIMULATION).

His research prototype tools in parallel and distributed computing have been disseminated to research institutions worldwide. He has performed research as an investigator on several research programs sponsored by US federal agencies including the DOE, DOD, DHS, and NSF.
