He is principal investigator for the Water Science Software Institute project, which seeks to build a cyberinfrastructure for managing, sharing and using water science data. As director of RENCI, he was instrumental in launching two major data science initiatives: The National Consortium for Data Science (NCDS), a public-private partnership to address big data challenges and opportunities in research and business; and iRODS, an effort to develop a branch of the popular integrated Rule-Oriented Data System as enterprise-quality software, complete with rigorous testing and a robust, feature-rich code base.

Dr. Ahalt serves as a member of the executive board of the iRODS Consortium, an international group focused on long-term sustainability of the iRODS data management platform. He is also a co-PI with the DataNet Federation Consortium, a National Science Foundation project to prototype an integrated platform for sharing, using and managing data across distances and scientific fields. Other leadership roles include past chair of the Coalition for Academic Scientific Computing, former co-chair of the Ohio Broadband Council, extramural member of the National Cancer Institute’s Advanced Biomedical Computing Center’s Oversight Committee, and member of the Council on Competitiveness High Performance Computing Advisory Committee. He has authored or co-authored more than 120 technical papers and been principal investigator or co-principal investigator on research grants totaling more than $17 million. His recent research publications have focused on decoupling data through encryption.

Before coming to RENCI in 2009, Dr. Ahalt was executive director of the Ohio Supercomputer Center (OSC) from 2003 – 2009 and a professor in the Department of Electrical and Computer Engineering at The Ohio State University for 22 years.  Ahalt launched several model programs at OSC, including Blue Collar Computing, a national program to bring high performance computing to a wide spectrum of industries and applications, and OSCnet, a leading high-speed research network for K-12 schools, higher education and economic development. He holds a Ph.D. in electrical and computer engineering from Clemson University and master’s and bachelor’s degrees in electrical engineering from Virginia Polytechnic Institute and State University.

ashokAshok 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.
