Lubomír Říha is the head of the Infrastructure Research Lab at IT4Innovations National Supercomputing Center. Previously he was a senior researcher in the Parallel Algorithms Research Lab at IT4Innovations, and a research scientist in the High Performance Computing Lab at George Washington University, ECE Department. He received his Ph.D. and M.Sc. degrees in Electrical Engineering from the Czech Technical University in Prague, Czech Republic, in 2011, and his Ph.D. degree in Computer Science from Bowie State University, USA. Currently he is a local principal investigator of the H2020 Center of Excellence project POP2. Previously he was an investigator of the FP7 EXA2CT project and the Intel Parallel Computing Center, as well as a local principal investigator of the H2020-FET HPC READEX project. He is also co-principal developer of the ESPRESO finite element library, which includes a parallel sparse solver designed for supercomputers with tens or hundreds of thousands of cores, with support for both GPU and Intel Xeon Phi accelerators. His research interests are optimization of HPC applications, energy efficient computing, acceleration of scientific and engineering applications using GPU and many-core accelerators, development of scalable linear solvers, parallel rendering on new HPC architectures, and signal and image processing.
