Bio

John W. Nehrbass obtained his Ph.D. in electrical engineering from The Ohio State University in 1996, M.S. in electrical engineering from Arizona State University in 1991 and B.S. in electrical engineering from Arizona State University in 1989. He is an expert at using high performance computers to speed up simulations by leveraging massively parallel DoD computer systems. He generates large data dome products for AFRL in support of many projects. Sensors simulated include electromagnetics - RADAR, LIDAR, IR, EO and others. Parallel calculations include parallel Matlab, parallel python, data formatting, GPU acceleration on deep learning systems and big data analysis. John frequently develops new algorithms and implements these in novel software packages. John created the latest version of MATLABMPI at MIT, created the parallel bench test in MATLAB for Mathworks, the AFacet tool sets and CAD modeling capabilities for the DOD and served as the lead scientist for the DoD HPCMP PETTT program from 1996 to 2006.
