Ashok Krishnamurthy became deputy director of RENCI in February 2013. Previously, he was director of research and scientific development at the Ohio Supercomputer Center (OSC) and an associate professor in the computer and electrical engineering department at The Ohio State University. He also served as OSC’s co-interim executive director from September 2009 to August 2012. His work focuses on managing and enhancing research partnerships with faculty at UNC Chapel Hill, Duke University and North Carolina State University, building relationships between RENCI and Triangle area businesses, and leading efforts to bring new federal research funding to RENCI and its partner institutions.
Krishnamurthy played a crucial role in establishing OSC’s successful industrial outreach initiative called Blue Collar Computing. The program targets small and medium-sized businesses that lack high performance computing resources, providing them with the training, expertise, and advanced technology tools they need to enhance their companies’ competitiveness. He also helped develop and deploy cyberinfrastructure that allows researchers to easily access and use computing and storage resources at OSC.
Before his work at OSC and OSU, he served as the academic lead for the U.S. Department of Defense (DoD) High Performance Computing Modernization Program in the Integrated Modeling and Test area. He has designed and provided numerous training courses for DoD User Groups on all aspects of the MATLAB programming language.
Krishnamurthy holds PhD and master’s degrees in electrical engineering from the University of Florida and a bachelor’s degree in electrical engineering from the Indian Institute of Technology. His areas of expertise include high performance computing (HPC), cyberinfrastructure, data exploitation, HPC in industry, American competitiveness initiatives, signal and image processing, and software development.
