# ABOUT EUCLID TECHLABS > DR. PAUL SCHOESSOW | VP, SCIENTIFIC COMPUTING

Paul Schoessow received his PhD in Experimental High Energy Physics in 1983 at the University of Illinois at Urbana-Champaign. He was with the High Energy Physics Division at Argonne National Laboratory from 1983-2000, working on the Argonne Wakefield Accelerator, Minos, and the Collider Detector at Fermilab. From 2000-2001 he was Senior Software Engineer at ETEC Systems Interconnect Products Group, Tucson, AZ, from 2002-2004 he was a Senior Scientist at Electro Magnetic Applications in Lakewood, CO, and from 2004-2006 he was a Principal Scientist at TechX Inc., Boulder,CO.

His main research activities have included numerical simulations of beam and laser-driven dielectric accelerating structures, wakefield acceleration experiments, accelerator controls and instrumentation, nonlinear effects in dielectric devices, applications of accelerator-based studies to instrumentation for cosmic ray physics and electromagnetic scattering problems for the Global Positioning System. He has also been involved in active microwave media based acceleration, novel rf sources, and microwave measurement techniques. His current interests include electromagnetic and N-body simulations on novel computing architectures (graphical processing units, parallella multicore single board computer.)
