Tinsley Oden Faculty Fellow (2006-2007) at University of Texas at Austin in the US.Mi-Young worked on population dynamics, epidemiology, and their finite element approximations. Mi-Young’s recent research concerns the development of high order discontinuous Galerkin finite element methods for the PDEs with a focus on the design of an efficient iterative linear solver for the high order discontinuous Galerkin approximation with Lagrange multiplier.

Misun Min
(Argonne National Lab, USA / mmin@mcs.anl.gov)

Misun Min is a Computational Mathematician in Mathematics and Computer Science Division at Argonne National Laboratory. She received a Ph.D. from Brown University in Applied Mathematics and joined Argonne National Laboratory in 2003. Her research focuses on challenging application problems governed by PDEs using state of the art high-order methods. A major part of her work in recent years is directed towards performance and scalability, whether using millions of CPUs or tens of thousands of GPUs. She is the Argonne PI for the U.S. Department of Energy (DOE)’s Exascale Computing Project (ECP), Center for Efficient Exascale Discretizations (CEED). Dr. Min’s software development effort includes NekCEM, NekLBM, and Nek5000/RS. She is the lead developer of NekCEM, which is an open-source high-order multiphysics code that supports computational electromagnetics, drift-diffusion, Schrodinger, and quantum density matrix equation solvers. She has also developed NekLBM, which is a spectral-element discontinous-Galerkin (SEDG) based lattice Boltzmann solver for the Navier-Stokes equations. She developed the first GPU-enabled variant of the Nek code suite using OpenACC for NekCEM simulations on Oak Ridge Leadership Computing Facility, Titan.
This work laid the foundation for subsequent OpenACC variants of Nek5000 and for the current developments in NekRS, which is the OCCA-based version of Nek5000 that is targeted for DOE’s exascale platforms. Dr. Min has led the scaling efforts for NekRS, with problems exceeding two billion spectral elements running on DOE’s leadership computers. Major application areas include reactor thermal hydraulics and wind energy.
