Kalyan S Perumalla
Distinguished R&D Staff Member
Dr. Perumalla holds additional appointments as Joint Full Professor in the School of Industrial and Systems Engineering at the University of Tennessee, Knoxville, and as Adjunct Professor in the School of Computational Sciences and Engineering at the Georgia Institute of Technology.
Prior to his research career at ORNL since 2005, he held full-time research appointments since 1997 at the Georgia Institute of Technology. He also served as Fellow of the Institute of Advanced Study at Durham University, UK, and as member of the National Academies’ Technical Advisory Boards for the U.S. Army Research Laboratory.
Dr. Perumalla is among the first recipients of the U.S. Department of Energy Early Career Award in Advanced Scientific Computing Research ($2.5 million for research over 5 years). Over the past 23 years, he has served as a principal investigator (PI) or co-PI on several research projects sponsored by agencies including the Department of Energy, Department of Homeland Security, Air Force, DARPA, Army Research Laboratory, National Science Foundation, and industry.
He is the author of “Introduction to Reversible Computing,” a seminal book in the fundamental theory and analysis of energy in computation. He co-authored another book, three book chapters, and over 125 articles in conferences and journals. He has delivered several advanced tutorials and lectures in defense simulation technologies, parallel systems, and reversible computing. Five (5) of his co-authored papers received the best paper awards, in 1999, 2002, 2005, 2008, and 2014.
Dr. Perumalla serves on international conference program committees and editorial boards of journals. He also held leadership roles as program chair or co-chair of multiple international conferences spanning areas from parallel simulation to cybersecurity.
Some of his research tools in parallel and distributed computing have been disseminated to research institutions worldwide. His algorithms and software prototypes have been scaled to over 200,000 processor cores and 1000’s of GPUs on large supercomputing systems, including the Oak Ridge Leadership Computing Facility’s Jaguar, Titan, and Summit series of supercomputers.
Dr. Perumalla earned his Ph.D. in computer science from the Georgia Institute of Technology in 1999. He is certified in Agile Development technologies as a Certified ScrumMaster, a Certified Scrum Product Owner, and a Certified Scrum-at-Scale Practitioner.
