# Peter Braam

Peter J. Braam is a Dutch-American computer scientist, mathematician and entrepreneur known for his contributions to large-scale computing systems. he has held academic positions at institutions such as the University of Utah, the University of Oxford and Carnegie Mellon University. In the industry, Braam is recognized for creating the Lustre parallel file system, widely used in high-performance computing (HPC) environments.

## Early life and education

Braam was born in Utrecht, Netherlands. He completed his undergraduate studies at Utrecht University in 1984. He pursued doctoral research under the supervision of Sir Michael Atiyah at the University of Oxford, earning his DPhil in 1987 with a thesis titled Magnetic Monopoles and Hyperbolic Three-manifolds.

## Academic Career

Following his doctorate, Braam became a Junior Research Fellow at Merton College, Oxford, and a C&C Huygens Fellow of the Netherlands Science Foundation. He later served as a tenured associate professor at the University of Utah and as a university lecturer and tutorial fellow at St Catherine’s College, Oxford. His research during this period encompassed differential topology, gauge theories, conformal field theories, algebraic geometry, and partial differential equations.

## Industry Contributions

Transitioning to the computing industry, Braam joined Carnegie Mellon University as a Senior Systems Scientist, where he led the Coda project and developed the InterMezzo (file system). In 1999, he introduced the Lustre (file system), an open-source parallel distributed file system designed for supercomputing applications. Lustre has been adopted by numerous top-tier supercomputers and is available as a service in Amazon Web Services. Braam founded or co-founded six startup companies, with four of them having their assets acquired. He has held executive roles at companies including Turbolinux, Sun Microsystems, and Xyratex. His work on Lustre and other storage solutions has significantly impacted the HPC community.

## Recent Activities

From 2013 to 2018 Braam has collaborated with the University of Cambridge on the Square Kilometre Array radio telescope project, focusing on data-intensive computing challenges. He has also served as a consultant to partners in the founding committee of Horizon 2020and the European Processor Initiative. He was a Visiting Professor in the Department of Physics at the University of Oxford from 2019-2025, and at Waseda University from 2022. His research interests include programming languages, parallelism, storage, and the application of machine learning in scientific contexts.

## Philanthrophy

Braam has endowed the Peter J. Braam Junior Research Fellowship and Graduate Scholarship in Human Wellbeing at Merton College, Oxford. These initiatives support early-career researchers and contribute to studies aimed at improving human wellbeing.
