American Chemical Society Graduate Students Benefit from SDSC Support

October 23, 2019

Oct. 23, 2019 — San Diego Supercomputer Center Director Michael Norman recently awarded two American Chemical Society (ACS) graduate students of the PHYS Division with 100,000 core hours and 500 gigabytes of storage on the Center’s Comet supercomputer. The awardees are Brooke Husic of Stanford University, and Marc Hamilton Garner of the University of Copenhagen.

The ACS awards encourage graduate work in theoretical chemistry, as well as recognize research accomplishments within the ACS Subdivision of Theoretical Chemistry.

“We had a record number of 35 applicants for this award and it would not have been the same without SDSC’s generous donation of time and storage on Comet,” said Francesco Paesani, a UC San Diego professor of chemistry and chair of the ACS Theoretical Chemistry Subdivision. “The pool of applicants was outstanding and it was exciting to learn about so many different and important contributions to the field of theoretical chemistry by so many young researchers. The future of theoretical chemistry is definitely in good hands!”

Husic, a Stanford PhD candidate in chemistry, said she plans to use her Comet allocation to better understand proteins and how they obtain their native structure by creating computational simulations.

“In my research, I have improved and designed mathematical architectures that yield easily interpretable and accurate models,” she explained. “Comet will make this research possible by providing the resources to create systems for testing methods and to search for accurate, highly detailed models of protein systems.”

Garner, a molecular electronics theorist at the University of Copenhagen, focused his Comet proposal on examining electrically insulating molecules.  Garner has already demonstrated one strategy for designing small insulating silicon-based molecules, but Comet will now allow him to screen thousands of potentially insulating carbon, silicon, and germanium-based molecules with different substituents.

In the development of the next generation of electronic devices, it is a fundamental challenge to control and minimize the leakage current that flows through parts of the device where it shouldn’t,” said Garner. “This problem happens due to a phenomenon called quantum tunneling when devices reach the scale of a few nanometers. Our work on Comet will help us better understand how to suppress this phenomenon, and find a solution to this fundamental research problem that will be important for making the next generation of electronic technology.”
