What They Are Doing Now: Emily DeCrescenzo Henriksen

Emily DeCrescenzo Henriksen (Ph.D. 2008) obtained her PhD from the Department of Microbiology in 2008 with Dr. Joy Doran-Peterson and is currently working at the Idaho National Laboratory. After completing a two-year postdoctoral position, Emily will transition to a staff scientist position at INL in August 2010. Emily continues to work on biofuels, studying extremophilic enzymes and their applications in bioethanol production.

What They Are Doing Now: Kate Brandon

Kate Brandon (M.S. 2008). After graduating with her Masters in December 2008, Kate Brandon started working at Novozymes, the world's leading enzyme supplier (located outside Raleigh, NC). As an associate scientist in the Enzyme Application R&D department, she has continued to work on enabling the biomass to ethanol industry, research she started in Dr. Joy Doran Peterson's lab. In early 2010, Novozymes launched Cellic CTec 2, the first commerically viable enzyme solution for second generation biofuels, a product she helped to develop and qualify.

What They Are Doing Now: Andrea Zbell

Andrea Zbell (Ph.D, 2008) is currently a postdoctoral associate in Dr. Phil Rather’s lab at Emory University (Atlanta, GA), where she has been studying biofilm formation by Acinetobacter baumannii. Indeed Dr. Rather recently presented a seminar to our (UGA) Microbiology Department, and a portion of the presented work was Andrea’s. Andrea is currently writing a manuscript about this work. While conducting the postdoctoral research in Atlanta, Andrea also taught as an adjunct faculty member at Southern Catholic College, in Dawsonville, GA.

What They Are Doing Now: Todd Smith (PhD 2009)

Todd Smith (PhD, 2009) After studying the regulation of flagellar genes in Helicobacter pylori with Dr. Tim Hoover, Todd was awarded an American Society for Microbiology Post-doctoral Fellowship in Infectious Disease and Public Health Microbiology. This two-year fellowship must be carried out at one of the Center for Disease Control and Prevention's national laboratories. Todd chose to work at the CDC in Atlanta with Dr. Charles Rupprecht in the Rabies Program as part of the Division of High Consequence Pathogens and Pathology.

What They Are Doing Now: Michael Gatlin (PhD 2009)

Michael Gatlin (Ph.D. 2009) Michael’s dissertation research with Dan Colley was on host immunogenetics in relationship to resistance to reinfection by schistosomes. His work followed up on 40 years of research by Dan on the immunology of schistosomiasis. As fate would have it, Michael’s postdoctoral research in Nancy Manley's lab at UGA on the developmental biology of the thymus was in the same area as Dan’s work 41 years ago, i.e. lymphocyte development in the thymus!

What They Are Doing Now: Laura E. Williams (PhD 2009)

Laura E. Williams (PhD 2009). After finishing her PhD with Dr. Anne Summers, Laura started her postdoctoral research in the laboratory of Jennifer Wernegreen's Laboratory (originally located at the Marine Biological Laboratory in Woods Hole, Mass., but since moved to the Institute for Genome Sciences and Policy, Duke University, Durham, N.C.). Her research focuses on genome evolution in Blochmannia, which are bacterial endosymbionts of carpenter ants.
