ROLE: Code Dev

SKILLS: C++, FORTRAN, Python, HPC, Machine Learning

SUBFIELD: ML for Astro, MHD code dev.

SC23 paper: link

We're developing an updated version of the WOMBAT MHD code based on HPE's open source Dragon framework for multiprocessing. The new framework allows for in-situ ML analysis and simulation control. We're developing a surrogate model project that will take the burden off of solving dynamically uninteresting regions by approximating them with a neural network.
