Andrew Christlieb currently serves as the Director of the Center for Hierarchical and Robust Modeling of Non-Equilibrium Transport (CHaRMNET), one of four Department of Energy Mathematical Multifaceted Integrated Capability Centers. In 2001, he received his PhD in Mathematics from the University of Wisconsin. After completing two post-docs at the University of Michigan (one in aerospace and one in mathematics), in 2006 he began his career at Michigan State University. In 2007, He was recognized by the Young Investigator Program (YIP) of the Air Force Office Of Scientific Research. From 2007-2011 he was an Intergovernmental Personnel Act (IPA) with Kirtland Air Force Base. His core research interests are scalable implicit algorithms, high-order structure/asymptotic preserving methods for both kinetic and fluid models, fast integral equations methods, particle methods, blended computing paradigms, and structure-preserving machine learning. His group has been recognized by the National Science Foundation, Air Force Office of Scientific Research, Office of Navel Research, and the Department of Energy for their work on high order methods and novel approaches to multi-scale problems in plasma and material science. Dr. Christlieb has graduated 22 PhD students and mentored 17 post-docs who have gone on to positions in industry, universities and the national labs. He is currently a University Foundation Professor of Mathematics at Michigan State University and from 2015-2021, Dr. Christlieb served as the founding chair of the Department of Computational Mathematics, Science and Engineering at Michigan State University.

Brian O'Shea is a computational and theoretical astrophysicist studying cosmological structure formation, including galaxy formation, the behavior of the hot, diffuse plasma in the intergalactic medium and within galaxy clusters, and (more recently) terrestrial high energy density plasma physics phenomena. He is also a co-author of several open source software tools including the Enzo, Enzo-E, and Athena-PK codes, an expert in high performance computing, and an advocate for open-source computing and open-source science. He received his B.S. in Engineering Physics at the University of Illinois in Urbana-Champaign (UIUC) in 2000, and his PhD in physics from UIUC in 2005. Following that, he was a Director's Postdoctoral Fellow at Los Alamos National Laboratory, with a joint appointment between the Theoretical Astrophysics Group and the Applied Physics Division. Since 2008, he has been a member of the faculty at Michigan State University, with a joint appointment between the Department of Computational Mathematics, Science, and Engineering (2015-present), the Department of Physics and Astronomy (2008-present), and the National Superconducting Cyclotron Laboratory (2014-present). From 2008-2015, Dr. O'Shea was a member of Lyman Briggs College. He has authored or co-authored over 100 peer-reviewed journal articles in astrophysics, computer science, and education research journals, and has received a variety of awards for his teaching and public outreach efforts. In 2016, he became a Fellow of the American Physical Society, and in 2019 he became the Director of MSU's Institute for Cyber-Enabled Research.
