Mike Hackemack (PhD). Mike worked on Sn transport discretizations for arbitrary polygons/polyhedra. We notably extended Adams’ PWLD method to a quadratic serendipity version. Mike also worked on diffusion synthetic acceleration and mesh adaptivity, in direct continuation of the PhD work of Yaqi and Bruno. Mike’s work led to 1 journal publication.
Mike is now staff member at KAPL (naval propulsion lab).

Peter Maginot (MS+PhD). For his MS, Peter worked on positivity-preserving discretizations of the transport equation (positivity of the solution in important in of itself, but lack thereof can cause serious numerical problems, for instance, in radiative transfer applications). For his PhD, Peter continued working on quadrature-based positivity and developed a high-order in space+time code for radiative transfer. His work led to 3 journal articles.
Peter went on to LLNL, first as a post-doc, then as a staff member. He is now at LANL.

Vijay Mahadevan (MS+PhD). My second PhD student. What great fun we had developing KARMA (Kode for Advanced Reactor Modeling and Analysis), making making high-end third party libraries (libmesh, PETSc, SLEPc, gmsh, tinyxml, …) talk to one another. KARMA was a mini-MOOSE, which we started independently of INL at around the same time. We did a lot of JFNK and Aitken-accelerated Picard and published 2 journal articles.
Vijay became a Givens Fellow at Argonne National Lab (ANL). Receiving a mathematical post-doctoral award is an outstanding achievement for a nuclear engineering. Well done breaking all sorts of barriers! Vijay was then hired by ANL and leads the SIGMA project.

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.
