Emory Chemistry Students Celebrate NSF GRFP Awards

Congratulations to Dayna Patterson (Weinert Group) and Kevin Hoang (EC 17′; Davies Group) for being awarded 2018 Graduate Research Fellowships from the National Science Foundation!

Congratulations also to Brendan Deal (Salaita Group) and Michael Hollerbach (Chemistry Graduate Program entering class of 2018) who received Honorable Mentions.

For the 2016 competition, NSF received over 12,000 applications and made 2,000 award offers.

The NSF Graduate Research Fellowship Program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based Master’s and doctoral degrees at accredited United States institutions. As the oldest graduate fellowship of its kind, the GRFP has a long history of selecting recipients who achieve high levels of success in their future academic and professional careers.

Meet the Honorees

Dayna Patterson came to Emory from Houston Baptist University where she had the opportunity to engage in undergraduate research with the Welch Foundation and as an NSF REU participant at Baylor University. Her research in  the Weinert Group focuses on understanding how bacteria change their phenotypes in response to environmental signals. In January 2018, Dayna received the Carl Storm Underrepresented Minority Fellowship to attend the Gordon Research Conference on Metals in Biology and share her research. She has also shared her research with the Atlanta community through the Atlanta Science Festival. She is the current treasurer for Pi Alpha Chemical Society and an associate fellow with the NIH-funded Initiative to Maximize Student Development.

Kevin Hoang conducted undergraduate research in the Davies Group at Emory and graduated in 2017 with a B.S. in chemistry. He is now at Yale University in the Herzon Laboratory.

Brendan Deal is a second year Ph.D. candidate in the lab of Dr. Khalid Salaita. He completed his undergraduate studies at Davidson College just outside of Charlotte, North Carolina. Brendan’s research is focused on the development of DNA-nanoparticle conjugates with potential applications in the fields of medicine and biotechnology.

 

Michael Hollerbach will be joining Emory this summer after receiving a B.S. in Biochemistry from the College of Charleston in South Carolina.  He chose Emory after seeing all of the exciting research opportunities and looks forward to participating in upcoming research rotations, starting with a summer rotation in the McDonald Group.  His research interests are in Organic Chemistry with a focus on small molecule synthesis and methodology development.  Currently, he is teaching Honors Chemistry at a local high school and wrapping up his undergraduate research at the College of Charleston. At Emory, he looks forward to the opportunity to share his love of Chemistry as a TA and to participate in outreach in the Atlanta community.

Graduate Student Spotlight Round-Up

The Emory Department of Chemistry is an epicenter of cutting-edge research in organic, inorganic, biomolecular, and physical chemistry fueled by its motivated and passionate graduate students. We have featured a few outstanding graduate students in previous blogs who embody the mission of our department to engage in teaching and research efforts as a collaborative scientific community. With Recruitment Weekend kicking off today, it is the perfect time to reflect on some of the accomplishments and experiences of a few of our graduate students.

Roxanne Glazier

Roxanne Glazier of the Salaita Group is a student in the Biomedical Engineering Program, a joint graduate program shared by Emory and Georgia Tech. For her research on developing novel methods to elucidate the mechanobiology of podosomes, Roxanne was recognized with the NSF Graduate Research Fellowship, a funding opportunity providing financial support to promising scientists early in their careers.

 

 

Robert Kubiak

Robert Kubiak of the Davies Group joined the Chemistry PhD program at Emory after serving as a platoon senior medic in the Army’s 3rd Ranger Battalion. His research project focuses on developing novel catalysts for N-sulfonyltriazoles-nitrogen-based compounds, with an ultimate goal of saving time and money in pharmaceutical synthetic processes.

 

 

 

Brian Hays

Brian Hays of the Widicus Weaver Group defended his thesis in April 2015 and, a year later, was recognized as the winner of the American Chemical Society’s Astrochemistry Dissertation Award. His award-winning research was focused on making and examining unstable molecules for their potential to lead to prebiotic molecules in space.

 

 

Yang Liu

Yang Liu of the Salaita Group defended his thesis, “Developing Nanoparticle-based Tools to Investigate Mechanotransduction at the Living/Nonliving Interface” in September 2016. In addition to his research on how our immune system can recognize and eliminate pathogens or cancer cells, he helped developed a technique for using single elastic molecules, such as DNA, protein, and polymer, as sensors to visualize membrane receptor mediated forces.

 

Looking Back on 2017

Happy New Year! As we welcome 2018, let’s reflect on some of the great things that happened during 2017.
