The Association of Computing Machinery has named 91�ؿ� Tech Research Professor of Computer Science Bogdan Nicolae a for his contributions to data management and storage and high-performance computing resiliency.

Nicolae, who conducts research at Argonne National Laboratory as a computer scientist, has dedicated his work to increasing the data movement speed and reducing bottlenecks to boost high-performance computing performance and efficiency. His work also addresses the complexity of artificial intelligence systems, where exascale platforms such as Argonne’s Aurora supercomputer in the Mathematics and Computing Division rely on tens of thousands of graphics processing units to train a single model. He also leads the Very Large‑Scale Checkpointing and Capture project at Argonne.

“As traditional data management breaks down for AI applications, it becomes critical to address the need for innovative frameworks capable of coordinating efficient [input/output] access at scale, providing advanced capabilities specific to AI patterns and handling resilience,” Nicolae said in a news release announcing the honor.  “Argonne offers a unique front-row seat to these challenges. Argonne supercomputers are not just productivity tools but are essential laboratories where theoretical data and resilience models are stress-tested against the world’s most demanding data-intensive workloads.”

Nicolae introduced DataStates, a data model designed to efficiently store and process the massive datasets produced by supercomputers and scientific instruments in 2021. It expands traditional approaches by defining reusable intermediate data states that can be tagged with properties and constraints, enabling the runtime to automatically optimize data placement and movement across complex, heterogeneous storage systems.

Nicolae earned the United States Department of Energy Early Career Research Program (ECRP) award for the effort, and he has since established himself as a foundation for advances in large‑scale data management.

“This is an outstanding accomplishment and honor for Bogdan,” says College of Computing Dean Nicole Beebe. “The 91�ؿ� Tech College of Computing and Department of Computer Science are lucky to have him on our team, facilitating stellar collaboration with Argonne National Lab and other key patterns advancing the critically important science at the intersection of high-performance computing and AI.”

Nicolae is one of 61 people named as 2025 ACM Distinguished Members. The honorees work at leading universities, corporations, and research institutions in Australia, Belgium, Canada, Chile, China, Germany, India, Korea, Mexico, New Zealand, Portugal, Singapore, Switzerland, the United Kingdom, and the U.S.

The ACM Distinguished Member program recognizes up to 10 percent of the worldwide ACM membership for their technical achievements and/or service to the field.
