I’m a Computational Scientist in the AI/ML group at the Leadership Computing Facility (ALCF) at Argonne National Laboratory (ANL).
I’m generally interested in training large models on supercomputers and co-lead the Models / Pre-Training group of the AuroraGPT project.
I received my PhD in Physics from the University of Iowa in 2019 for my work on using ML to accelerate MCMC simulations in Lattice Quantum Chromodynamics (l2hmc-qcd).
