Yaqi Wang (MS+PhD). My first PhD student! Back in 2006, we were among the first ones to do mesh adaptivity for Sn transport on unstructured grids, using high-order finite elements. Whoop!!! In addition, we developed a robust and useful diffusion-preconditioned for transport based on discontinuous finite elements. It is used in several radiation transport codes today. We published a total of 7 journal articles (and numerous conference proceedings).
Yaqi was hired as a staff by INL. He is now the lead architect of their neutronics code, RattleSNake, based on the MOOSE multiphysics platform.
