Dr. Youngjun Choi

Dr. Youngjun Choi joined Michigan State University in the summer of 2014 as a research specialist. Previously, he was a research scientist at Tech-X in Boulder, CO. He received a PhD in Aerospace engineering from University of Michigan in 2008. His IMG_1992research interests include: magnetic fields in strongly coupled plasmas, abnormal electron transport in Hall effect thrusters, and high-performance computing using multicores and accelerators.

Dr. Choi is currently investigating the properties of magnetized ultracold plasmas, characteristics of the dynamic structure factor and dynamic local field correction of plasmas across coupling regimes, is  working on development of a parallel electrostatic Poisson solver and is involved in the open-source development of Sarkas. In addition, he provides guidance to MSU people to use high-performance computers and works with them to refine their research.
