Dr. Sadayappan joined The Ohio State University in 1983 as an assistant professor, became an associate professor in 1990, and, since 1997, has been a professor in the Department of Computer Science and Engineering. His primary research interests center around performance optimization and compiler/runtime systems for high-performance computing, with special emphasis on high-performance frameworks that enable high productivity for application developers in scientific computing. In 2003, Dr. Sadayappan led a consortium of two other universities and two national laboratories that developed the Tensor Contraction Engine, a software tool that automatically generates the computer code that chemists, physicists, and materials scientists need to model the structure and interaction of complex molecules. Current research projects include studies of high-productivity high-performance computing using GPUs/accelerators, global graphs, petascale simulations of quantum systems, and customizable domain-specific computing. All of these projects are funded by the NSF. Dr. Sadayappan is the author of more than 200 peer-reviewed articles and papers in proceedings. He received his B.Tech. from the Indian Institute of Technology, Madras, and his M.S. and Ph.D. degrees from the State University of New York at Stony Brook.
