Sandia Computing Researcher Wins DOE Early Career Research Program Award

October 9, 2017

ALBUQUERQUE, N.M., Oct. 9, 2017 — Sandia National Laboratories researcher Tim Wildey has received a 2017 Early Career Research Program award from the Department of Energy’s Office of Science.

Wildey is Sandia’s first winner of the Advanced Scientific Computing Research branch of the prestigious program, said manager Daniel Turner.

The national award, now in its eighth year, provides researchers a grant of $500,000 yearly for five years. Its intent is “to identify and provide support to those researchers early in their careers who have the potential to develop new scientific ideas, promote them and convince their peers to pursue them as new directions,” according to the Office of Science.

Wildey’s proposed research seeks to develop data-informed multiscale modeling and simulation that will be mathematically consistent and more robust than current practices.

His research over the past few years has focused on developing mathematical and computational frameworks that quantify the amount of uncertainty present in a problem. That uncertainty is then included in his mission-related modeling and simulation.

Wildey anticipates that using complex multiphysics applications to inform high-consequence decisions will require moving beyond “forward simulation” — the practice of assuming all a model’s input parameters are known and then using the model to make predictions about objects of interest.

“Moving beyond forward simulation means that we no longer assume that we precisely know these model inputs and we instead seek to infer information about them from experimental data,” he said.

“Many problems in materials science, subsurface flow and mechanics and magnetohydrodynamics are best described by multiphysics, which involves multiple physical models or multiple physical phenomena, and multiscale models,” he said. “These problems are challenging to simulate because they incorporate detailed physical interactions across a wide range of length and time scales. This research will pursue mathematically rigorous and computationally efficient approaches for predicting the properties and behavior of realistic, complex multiphysics applications.”

His proposed integration of advances in numerical discretization, uncertainty quantification, data assimilation and model adaptation should achieve models that can better predict outcomes.

“This project integrates some of that foundational work with ideas we’ve been exploring at Sandia to benefit a wide range of mission applications that support the science and national security missions of Advanced Scientific Computer Research and the DOE,” Wildey said.

Wildey joined Sandia in January 2011 after a postdoctoral fellowship at the University of Texas at Austin, receiving a Master of Science and doctorate at Colorado State University and a bachelor’s degree at Michigan State University, all in mathematics.

DOE Early Career grants are available in the program areas of Advanced Scientific Computing Research, Biological and Environmental Research, Basic Energy Sciences, Fusion Energy Sciences, High Energy Physics and Nuclear Physics.

HPC Serves as a ‘Rosetta Stone’ for the Information Age

July 12, 2018

In an age defined and transformed by its data, several large-scale scientific instruments around the globe might be viewed as a ‘mother lode’ of precious data. With names seemingly created for a ‘techno-speak’ glossary, these interferometers, cyclotrons, sequencers, solenoids, satellite altimeters, and cryo-electron microscopes are churning out data in previously unthinkable and seemingly incomprehensible quantities -- billions, trillions and quadrillions of bits and bytes of electro-magnetic code.
