Clayton G. Webster, Ph.D.

Senior Mathematician & Professor

FY13 announcements

  • DOE Advanced Scientific Computing Research (ASCR) Award FWP #ERKJ259: FY14-FY17

I am the Lead PI and Research Coordinator under ASCR's "Uncertainty Quantification Methodologies for Enabling Extreme-Scale Science." The project, entitled A Mathematical Environment for Quantifying Uncertainty: Integrated aNd Optimized at the EXtreme Scale (EQUINOX), includes co-PIs Prof. Max Gunzburger from Florida State University, Prof. Jeff Wu from Georgia Tech, and Drs. Rick Archibald and Eric Phipps from ORNL and Sandia National Labs respectively.

  • Kavli Frontiers of Science Fellow, National Academy of Sciences

I have been invited in participate in the German-American Kavli Frontiers of Science symposium, which is jointly organized by the Alexander von Humboldt Foundation and the National Academy of Sciences. The symposium

will be held at the Beckman Center on the UC Irvine campus from April 4-6, 2014, and serves to brings together outstanding young scientists to discuss exciting advances and opportunities in a broad range of disciplines. A committee of NAS members selects the participants from among young researchers who have already made recognized contributions to science, including recipients of major fellowships and awards.

  • Invited Talks at both ASCR and AFOSR Annual Mathematics PI Meetings

I was invited to present our work at both the ASCR (DOE) and AFOSR (DOD) Mathematics Annual Meetings,

held in Albuqerque, NM (Aug. 6-8, 2013) and Washington, DC (July 29-Aug 2, 2013). Unfortunately, I was unable to attend due to the expected arrival of our first son Liam James Webster. Instead, I sent along a poster and a talk which you are welcome to download.

  • Organizing Committee, SIAM Conference on Uncertainty Quantification

I have been invited to serve on the organizing committee of the SIAM Conference on Uncertainty Quantification, March 31 - April 3, 2014, at the Hyatt Regency Hotel in Savannah, GA.

  • ASCR Exascale Math Working Group (EMWG) Committee

I have been invited to serve as a member of the EMWG, responsible for: (1) Analyze potential gaps in current thinking about applied mathematics for the exascale; (2) Identify new algorithmic approaches that address exascale challenges; (3) Identify mathematics to address new scientific questions accessible at exascale, especially through integration across applied mathematics sub-disciplines; (3) Identify a holistic, co-design approach for applied mathematics exascale research that more directly involves a dialogue with application scientists and computer scientists; and (4) Submit a report of the findings to the DOE Office of Science. The EMWG Workshop is being held from August 21-22, 2013.

  • Joining the Editorial Board, SIAM Journal on Uncertainty Quantification

I have been invited to serve on the inaggural editorial board of the SIAM Journal on Uncertainty Quantifcation (JUQ), which is dedicated to nurturing synergistic interactions between the mathematical, statistical, computational, and applications communities involved in uncertainty quantification and related areas.

  • Joining the Editorial Board, SIAM Journal on Numerical Analysis

I have been invited to serve on the editorial of the SIAM Journal on Numerical Analysis (SINUM), which

contains research articles on the development and analysis of numerical methods. As an associate editor I am responsible for papers related to stochastic (partial) differential equtaions, high-dimensional approximation theory and uncertainty quantification.

  • Promotion to Senior Staff Scientist, Level IV

My promotion to Senior Staff Scientist, Level 4, has been approved and will take effect March 1, 2013. This is for recognition of my extraordinary research and funding productivity.

  • Team Leader, Predictive Methods Team (Applied Mathematics)

Effective January 1, 2013, I will be leading a new Predictive Methods Team (PMT) within the Applied Mathematics Group. The role of the PMT at ORNL is to develop innovative, massively scalable and resilient mathematical and computational approaches for scientific (model) discovery as well as decision-sciences. Our focus areas include uncertainty quantification, multi-scale/-physics, data analytics and large-scale solvers.

  • Joint Faculty Appointment, Department of Mathematics, University of Tennessee

I have accepted a joint faculty appointment as an Associate Professor in the Department of Mathematics, University of Tennessee. I am currently supervising two Ph.D. students, Nicholas Dexter and Peter Jantsch, as well as two postdoctoral fellows, Diego Galindo and Hoang Tran. A description of our research is given here.

  • DOD Air Force Office of Scientific Research (AFOSR) Award #1854-V521-12: FY13-FY16

I am the ORNL PI of the project entitled Generalized Mathematical and Computational Methods for Predictive Simulation of Stochastic Turbulent Systems. This work includes co-PIs Profs. Bill Layton and Catalin Trenchea from the Univeristy of Pittsburgh.

  • Distinguished Employee, Computing and Computational Sciences Directorate, ORNL

I was awarded the CCSD Distinguished Employee Award in November 2012 for my outstanding publication record and for my ability to attract new funding sources, both national agencies and industrial partnerships, to Oak Ridge National Laboratory.
