Fusion Deep Learning


William Tang

William Tang of Princeton University is a Principal Research Physicist at the Princeton Plasma Physics Laboratory for which he served as Chief Scientist (1997-2009) and Head, Theory Department (1990-2002). He is Lecturer with Rank & Title of Professor in the Plasma Physics Section of the Department of Astrophysical Sciences, Participating Faculty at the Center for Statistics and Machine Learning (CSML), and member of the Executive Board for the "Princeton Institute for Computational Science and Engineering (PICSciE)," which he helped establish and served as Associate Director (2003-2009). He received his PhD in Physics with his dissertation carried out at the University of California Lawrence Livermore National Laboratory within the Department of Applied Science founded by Edward Teller, and is a Fellow of the American Physical Society.

He is internationally recognized for expertise in the mathematical formalism as well as associated computational applications dealing with electromagnetic kinetic plasma behavior in complex geometries, and has well over 200 publications with an "h-index" or "impact factor" on Google Scholar Citations of 60 with over 14,300 citations that include 40 papers each with at least 100 citations. He was U.S. PI for the G8 Research Council's "Exascale Computing for Global Scale Issues" Project in Fusion Energy - an NSF-funded international HPC collaboration (2011-2014).

Prof. Tang has made original contributions in basic plasma physics, fusion energy science, interdisciplinary computational science, and artificial intelligence/deep learning -- with associated awards including:

  • the 2005 Chinese Institute of Engineers-USA Distinguished Achievement Award "for outstanding leadership in fusion research and contributions to fundamentals of plasma science."
  • the 2019 Global Impact Award from NVIDIA Corporation for "groundbreaking work in using GPU-accelerated computing to unleash deep learning neural networks for dramatically increasing the accuracy and speed in predicting disruptions in fusion systems."
  • the 2013 High Performance Computing Innovation Excellence Award from International Data Corporation for "using high-end supercomputing resources to carry out advanced simulations for the first time of confinement physics in large-scale magnetic fusion energy plasmas with unprecedented phase-space resolution and long temporal duration to deliver important new scientific insights."

Dr. Tang is the current leader of an AI/Deep Learning project that has produced a high-profile article in NATURE (April 2019) on "Predicting Disruptive Instabilities in Controlled Fusion Plasmas through Deep Learning" (J. Kates-Harbeck, A. Svyatkovskiy, W. Tang) that brings together the emergence of the exciting growth area of deep learning with an exemplar from the grand challenge area of clean energy via magnetic fusion. This work uniquely demonstrated for the first time that predictive software trained on one experimental device (e.g., the DIII-D tokamak in CA) to make accurate predictions on another (the larger and more powerful EUROFUSION JET tokamak in the UK). Moreover, it was the first FES DL code to efficiently utilize leadership class supercomputers (e.g., Titan, Summit in US; & Tsubame-3 in Japan) -- highlighted in his invited Keynote on “Deep Learning Acceleration of Progress toward Delivery of Fusion Energy" at the 2018 International Supercomputing Conference in Frankfurt, Germany. He is currently PI for prominent FES HPC Supercomputing discovery science projects including the ANL Early Science Project (ECP) on AURORA -- the first targeted DOE-SC Exascale System in 2021, the new “NESAP for Learning (N4L)” Project on the Perlumutter System at LBNL, and (as Co-PI with Zhihong Lin of UC Irvine) on the internationally top-rated SUMMIT System at ORNL.
