Summer School Leads

Julien Loiseau

CCS-7 Applied Computer Science.
Julien is a Computer Scientist with a background in High Performance Computing and simulation. He has experience in hybrid architectures and accelerated systems. His postdoctorate work focuses on FleCSPH, a tool for Smoothed Particles Hydrodynamics simulations based on the FleCSI framework from LANL. The intent is to provide an efficient and distributed tree data structure to FleCSI that allows the work to be offloaded to accelerators. The final goal of FleCSPH is to simulate large Astrophysics events.
Julien is an alumnus of the 2016 summer school class.

Hyun Lim

CCS-2 Computational Physics and Methods.
Hyun Lim is a staff scientist in CCS-2 with a background gravitational physics, astrophysics, and applied mathematics. He has experiences developing various multi-physics codes both Eulerian and Lagrangian frames to solve problems in astrophysics and magnetohydrodynamics. He also works on scalable numerical methods including adaptive mesh refinement and linear solvers.
