Argonne National Laboratory — Lemont, IL
I am a Computer Scientist in the AI/ML Group at Argonne National Laboratory (ALCF). My research interests include agentic AI systems for autonomous scientific discovery, large-scale distributed training, and data management for AI. I apply high-performance computing and deep learning to domain sciences including physics, chemistry, and materials science. I co-lead the MLPerf Storage Benchmarking group, developing benchmark suites for evaluating the performance of storage systems for AI applications.
