Distinguished Admiral Grace Hopper Fellowship
The Distinguished Admiral Grace Hopper Fellowship was established in 2015 with the goal of developing young computational scientists to make outstanding contributions in the area of HPC applications.
Upcoming or recent Ph.D. graduates in computational science disciplines, computer science or applied mathematics who have received their degree within the last three years are encouraged to apply. The successful applicant will work in a stimulating environment, can present results at major conference venues and establish strong connections to academic and industry partners. They will receive a competitive salary, relocation assistance, excellent benefits, frequent opportunities to travel and an opportunity to work in the San Francisco Bay Area.
In 2015, Taylor Barnes became the first recipient of the Grace Hopper Fellowship. He was responsible for enhancing the performance of materials science calculations on NERSC's Cori supercomputer, which was at that time the fifth most powerful supercomputer in the world. Specifically, he worked under the direction of Jack Deslippe to improve the parallelization of hybrid density functional theory (DFT) calculations in the popular open-source software package Quantum ESPRESSO. These efforts enabled him to decrease the time-to-solution for accurate simulations of condensed-phase systems by an order of magnitude. In collaboration with the research group of David Prendergast at the Molecular Foundry at Berkeley Lab, he used these computational advances to contribute to the development of rechargeable magnesium-ion batteries, which offer much greater volumetric energy densities than lithium-ion batteries, but which are currently commercially impractical due to the slow rate at which the magnesium ions travel through the cathode of the battery. After an extensive computational investigation of the pathways followed by magnesium ions through the cathode, he was able to identify specific pathways that are responsible for slowing the migration of the ions, thus providing crucial insight towards overcoming the barriers to the development of viable magnesium-ion batteries. Following his fellowship at NERSC, Taylor joined the Molecular Sciences Software Institute as a software scientist.
