Dale Welch

Dr. Welch joined the Computational Physics Group at Voss Scientific in 2005, where he serves as Computational Physics Division leader as well as principal investigator for multiple programs serving National Laboratories and Universities.  The group is involved with laser interaction with matter, fusion plasmas, charged-particle beam propagation in partially ionized gases, high-power particle beam accelerators and numerical analysis including the development of cutting-edge plasma simulation tools.  His personal work has been the investigation of beam transport in plasmas and gas, laser plasma interaction and beam acceleration and plasma modeling in pulsed-power machines and fusion implosions. Dr. Welch is leading development of the CHICAGO hybrid particle-in-cell code.
