Wahid Bhimji
Wahid Bhimji is acting Group Lead and a Big Data Architect in the Data and Analytics Services Group at NERSC. His interests include machine learning and data management. Recently he led several projects applying AI for science including deep learning at scale, generative models and probabilistic programming. He coordinates aspects of machine learning deployment for the Lab's CS-Area and NERSC: including the upcoming Perlmutter HPC system and plans for future NERSC machines. Previously he was user lead for the commissioning of Cori Phase 1, particularly data services, and for the Burst Buffer. Wahid has worked for many years in Scientific Computing and Data Analysis in Academia and the U.K. Government and has a Ph.D. in High-Energy Particle Physics.
Steve Farrell
Steve is a Machine Learning Engineer in the Data and Analytics Services group at NERSC. He supports machine learning and deep learning workflows on the NERSC supercomputers and collaborates with scientists for applied ML research.
Steve's background is in high energy experimental particle physics. As an undergrad in Minnesota, he worked on the MINOS experiment, SNEWS, and CLEAR. As a Ph.D. student at UC Irvine, he joined the ATLAS experiment at CERN, where he worked on searches for Supersymmetry. Finally, as a Postdoc at Berkeley Lab in the Physics Division, Steve worked on software and computing for the ATLAS experiment and machine learning R&D for HEP.
Steve maintains the Deep Learning software stack at NERSC, including Intel-optimized Tensorflow and PyTorch, scalable libraries for training such as Horovod and the Cray PE ML Plugin, and Jupyter notebook solutions for distributed ML on the Cori supercomputer. He is also compiling and maintaining a set of Deep Learning science benchmark applications for NERSC, to characterize the supercomputer systems and to guide optimization efforts to ensure that scientific applications run smoothly and efficiently. Finally, Steve provides training to the community through documentation, blog posts, workshops, and tutorials.
Stefan Kesselheim
I want to push the boundaries of what we can do with Artificial Intelligence (AI) methods. I pursue three directions: more prior knowledge, more compute and more fascinating questions.
Prior knowledge can look very different. It can be unlabelled or or weakly labelled data (e.g. noisy or unrelated labels), physical equations or symmetries, input data statistics or something completely different and requires the AI method to be tailored to it. The large amounts of related data or a large model complexity require using the game-changing capabilities of the Jülich Supercomputing Center. Integrating prior knowledge can vastly improve the data efficiency and allows researchers to apply AI methods to even more interesting, intriguing and impactful applications from all fields of science and engineering.
