About

I’m a physicist, computational scientist, and now software engineer. I build software that lets scientific AI run at the native scale of science: very large inputs, many GPUs, and models that respect physics.

Currently

Today, I’m a Senior Software Engineer for AI for Science at NVIDIA. Primarily, I work on PhysicsNeMo and related projects. PhysicsNeMo is the open-source framework for AI in physics and engineering.

Within PhysicsNeMo, I invented and architected ShardTensor, PhysicsNeMo’s domain-parallelism framework, which scales high-resolution scientific data past the memory limitations of a single GPU. I also designed and built our generic high-resolution datapipes, led performance work on the library, and co-authored the GeoTransolver surrogate model for CFD and CAE. Currently, I am the software architect of PhysicsNeMo.

Past Projects

I have worked on some fascinating projects in my past. Here’s a curated selection:

• At Argonne National Laboratory, I was a Computational Scientist and physicist from 2018 to 2024. I was the lead of AI software for the Aurora Supercomputer, which debuted at #2 on the TOP500. As part of that work, I developed and led multiple deep learning performance benchmarks both on single GPUs and at scale, up to thousands of GPUs, focusing on scientific applications that real Argonne users might encounter.
• While at Argonne, I also pursued fundamental research of neutrinoless double beta decay with the NEXT Collaboration, based in Spain. I developed novel techniques for sparse neural networks to detect signals of interest, and built prototype detectors for the next generations of searches. In 2021 I was awarded a Department of Energy Early Career Award for this research.
• In collaboration with A. Lovato at Argonne, we combined theoretical nuclear physics with machine learning techniques to publish some of the first solutions of nuclear many body problems with neural networks.
• Prior to my work at Argonne, I was a postdoc at Harvard University, working with Professor Roxanne Guenette (now at University of Manchester) on the MicroBooNE and NEXT experiments.
• My PhD research was at Yale University, with Professors Bonnie Fleming (now at University of Chicago) and Ornella Palamara (now at Fermilab) on MicroBooNE and ArgoNeuT. My dissertation research was the First Observation of Low Energy Electron Neutrinos in a Liquid Argon Time Projection Chamber.
