Dr. Mallikarjun (Arjun) Shankar is the Director of the National Center for Computational Sciences (NCCS) at Oak Ridge National Laboratory. Before taking on the Division Director role in 2024, Shankar served as the Section Head for the Advanced Technologies Section (ATS) in the NCCS and as the director of the Compute and Data Environment for Science (CADES) at ORNL. He is a distinguished R&D staff scientist.
Dr. Shankar received his B.Tech. from the Indian Institute of Technology, Mumbai, and his M.S. and Ph.D. in computer science from the University of Illinois, Urbana. After his doctoral research he worked in industry designing and building next-generation content distribution infrastructures. His research in the national laboratory setting has involved designing large-scale data analysis and modeling systems, sensor networking systems, energy grid monitoring and control frameworks, and deploying middleware to overlay data, computation, and control across systems and infrastructure. His sponsored R&D project outputs have several active users in the federal government as well as in the commercial sector. His research has resulted in over seventy peer-reviewed publications including those that address jointly modeling and simulating systems coupled with observational data, incorporating policy constraints, and creating scalable cross-facility data infrastructure.
