 JOANNE CHAPMAN (POstdoctoral researcher)  Jo works on characterizing the activity and evolution of antimicrobial peptides (AMPs) in  Drosophila  species. AMPs are small proteins that can directly kill or impede the growth of microorganisms. As such, they play an important role in innate immune defenses of plants and animals. Jo uses a combination of approaches, including functional assays of AMP activity in-vitro, in-vivo infection models involving RNAi gene silencing and CRISPR mediated gene editing, and bioinformatic analyses of AMP diversity and evolution. This will allow her understand the role AMPs play in negating the negative fitness consequences of pathogenic infection in  Drosophila .

 TOM HILL (postdoctoral Researcher)  Tom works on understanding the evolution of parasites and their hosts using bioinformatics. He studies the co-evolution of mushroom-feeding  D. innubila  and their parasites, including a DNA virus and male-killing  Wolbachia . He is currently assembling the  D. innubila  genome and identifying factors related to its ecology, such as genes involved in resistance to toxic mushrooms or immune system evolution. He is also working to understand transposable element host-pathogen co-evolution across different species of  Drosophila  using next generation sequencing.

 Sarah Mullinax (Self Graduate Student)  Sarah works on understanding the effects of antimicrobial peptide gene conversion on the  Drosophila  immune response. She focusses mainly on the AMP Diptericin. Diptericin is interesting because not only has there been five independent mutations of the same allele in  Drosophila  species, but there has also been a gene duplication event in  D. simulans. A mino acid polymorphism in Diptericin has previously been shown to predict the level of immune response upon infection with  Providencia rettgeri .

 Andrea Darby (NIH PreP Scholar)  Andrea Darby is a Las Vegas native that recently earned her B.S. in Biology with emphasis in Ecology and Evolution from the University of Nevada, Las Vegas. She will be applying to Biology PhD. programs in Fall 2018. Andrea plans to investigate the role of immunity and the gut microbiome of Drosophila melanogaster in adaptation to desiccation. In her spare time, she likes to cosplay, play video games, and pet dogs.

 Jenna Lea (Assistant Researcher)  Jenna recently graduated from the University of Georgia where she obtained a double major in Biology and Ecology. She is working as research assistant to understand the evolutionary genetics of meiotic drive in  Drosophila affinis . She will be spending the next year researching the molecular mechanisms, target gene and responder loci responsible for the varying effects on offspring sex ratio. Outside of the lab Jenna likes food, music, hiking and her cat Tuna.
