Jessie Uehling, Ph.D student (UPGG Ph.D. program), 2012- 2017, co-advised with Rytas Vilgalys

Research interests:  I joined the Program in Genetics and Genomics at Duke in fall of 2012 after receiving a BS in Botany and MSc in Mycology from Humboldt State University in Arcata, CA. My interests in tropical botany and mycology began during an influential summer I spent at a field research station in Panama as an undergraduate. I continued studying mutualistic symbiotic plants and fungi in the neotropics during my MSc, which focused on molecular ecology and systematics of the fungal genus Clavulina in Guyana. During my rotation in the Wernegreen lab I learned computational techniques to evaluate systematic questions using mitochondrial genomes from the ant genus Camponotus. My dissertation research is aimed at understanding the interactions of plant associated fungi with various bacteria including several endosymbionts. I am using a multi -omics approach to understand how bacterial fungal symbioses are established and maintained.

Carlton AdaCarlton_lab_sitems, Undergraduate Researcher, summer 2014 – Present


Research interests: Up to this point as an undergraduate, I have gained a genuine interest in the study of prokaryotic microbial communities and the defined interaction that these organisms have developed with associated eukaryotic organisms. More specifically though, within this association, topics such as the development of antibiotic resistance by associated bacterial strains both inside and outside of a eukaryotic host relationships, the ability of eukaryotic organisms to control the growth of bacteria, and the mechanism by which certain bacterial strains are able to employ the use of the essential cellular processes of associated eukaryotic organisms are all topics that fascinate me. In addition to this though, I am also interested in the fairly distinct topic of the involvement that epigenetic biomarkers have in defining a relationship between certain eukaryotes and prokaryotes in light of the measurable ways that epigenetic inheritance can influence phenotypic characteristics.
