Hai Ah is a computational physicist with a background in low-energy nuclear physics and high-performance computing. She is a co-PI of the Nuclear Structure and Nuclear Reactions DOE INCITE (Innovative and Novel Computational Impact on Theory and Experiment) project, the NUCLEI DOE SciDAC project, and worked for over six years at the Oak Ridge Leadership Computing Facility at ORNL prior to joining LANL.Hai Ah is team lead for the Trinity Center of Excellence, helping to prepare critical tri-lab ASC codes for Trinity and future architectures. She enjoys working with students and was chair of the SC Student Cluster Competition (2010, 2015), an intense undergraduate competition to prepare the next generation of HPC scientists.
Joe Schoonover

Joe Schoonover (2017)

CCS-2: COMPUTATIONAL PHYSICS AND METHODS
Joe studied Applied Mathematics and Physics as an undergraduate at Florida State University. Recently, he received a PhD in Geophysical Fluid Dynamics with a primary focus on inviscid flow separation mechanisms for baroclinic jets in rotating systems. This work necessitated the development of software that implements the Discontinuous Galerkin Spectral Element Method. Current interests are split between applications of the DGSEM to geophysical processes and an investigation of vorticity and gravity wave arrest mechanisms its impact on ocean energetics and long term oceanic transport pathways. The latter involves direct communication between small ( less than 1 km ) and large scale ( > 500 km ) fluid disturbances that requires large discrete systems in order to accurately model. This has motivated an investigation into parallelization strategies for the DGSEM.

Gabriel Rockefeller (2016)

XCP-1: LAGRANGIAN CODES
Gabe Rockefeller joined LANL in 2002 as a graduate student in the Theoretical Astrophysics group, where he studied supernovae, gamma-ray bursts, and the Galactic center using the smoothed particle hydrodynamics code SNSPH. He moved to the Computational Physics & Methods group (CCS-2) for a postdoctoral appointment in 2006, where he was an early member of the NuGrid collaboration on nucleosynthesis in astrophysical environments. After being hired as a staff member in CCS-2 in 2008, he contributed to the Jayenne Implicit Monte Carlo radiation transport code, including assisting in the development of a Cell-accelerated version for the Roadrunner supercomputer, and served as point of contact for the development team in 2015. He also contributed to the xRage and Cassio adaptive-mesh multiphysics codes developed by the Eulerian Applications Project, as integrator, tester, debugger, and as part of an effort to prepare those codes for emerging computing platforms.
