ALBUQUERQUE, N.M. -- Sandia National Laboratories has named Mercedes Taylor and Chen Wang its first Jill Hruby Fellows. The honorees have each been awarded a three-year postdoctoral fellowship in technical leadership, comprising national security-relevant research with an executive mentor.
Susan Seestrom, chief research officer and associate laboratories director for advanced science and technology, will mentor both Taylor and Wang. "Our goal is to provide our fellows with a stimulating opportunity that will allow them to exercise their clear talent and leadership potential," Seestrom said. "I look forward to them coming on board."
The Jill Hruby Fellowship is meant to encourage women to consider leadership in national security science and engineering. Hruby, the first woman to lead a national security laboratory, served as Sandia's director from 2015 to 2017. Applications for fellowships beginning October 2019 will be accepted until Nov. 1.
Mercedes Taylor, ion collector
Working as a chemist for the National Institutes of Health prior to graduate school, Taylor found herself drawn to the idea of a career in government research. "I loved the ability to pursue promising projects regardless of a corporate bottom line while still working in an environment of cutting-edge professional research," she said. Taylor went on to earn a doctorate in chemistry from the University of California, Berkeley.
Her ideal career path, she added, leads to a top position at a national laboratory, where she would head research that supports national security and global peace. An opportunity to work at Sandia seemed a perfect fit. "The Jill Hruby Fellowship will give me the chance to establish that career."
Over the next three years, her research will aim to develop new porous plastics that purify water by soaking up ions -- electrically charged atoms and molecules -- with an emphasis on negatively charged ions, called anions. Materials that can target a particular ion selectively, even in the presence of many other ions, could be especially useful to national security, by identifying chemical warfare agents, radioactive material or harmful natural impurities, like arsenic in a water sample. Current technologies to remove various ions from water on an industrial scale leave much to be desired, so the work could also find practical use in desalination plants.
As climate change and population growth are projected to make drinking water scarcer globally over the coming decades, Taylor hopes her work will provide relief and security.
Chen Wang, soot detective
Chen Wang, who earned a doctorate in materials science at the University of California, Irvine, will begin her fellowship pursuing the understanding of pollution from combustion engine systems to help to improve energy efficiency and safety, and reduce environmental impact.
To achieve that, Wang will seek to further engineers' understanding of how the smallest particles of soot originate inside a flame. That's a complicated question. A fire is a tangle of physical and chemical changes that feed off each other and often occur simultaneously. Much research in this field, including a new Sandia-led theory recently published in Science, has been conducted by characterizing the mass of particles extracted from a flame. Wang's research will complement that knowledge by capturing molecular-resolution images of these tiny particles so she can inform computer simulations that model how the particles interact with one other. She will collaborate with Sandia's Combustion Research Facility in Livermore, California, a specialized laboratory with equipment that can mimic the environment inside an engine.
Wang says the Hruby Fellowship will help her continue to encourage public interest in science and environmental issues while promoting the public image of female scientists. As a graduate student and through the Association of Women in Science, she organized science activities for kids and families in downtown Riverside, California. She later expanded to large workshops held at a Discovery Cube children's science museum in Santa Ana, California.
"I saw it as an opportunity to do something more, to build the foundation of what the Hruby Fellowship will become in coming years."
The Jill Hruby Fellowship is supported by Laboratory Directed Research and Development.
