My research is focused on understanding how genetic diversity of pawpaw (Asimina triloba) is partitioned within and among natural populations throughout its range in North America. It has long been thought that pawpaw, which is valued for its flavorful fruit, was dispersed long distances by indigenous humans long before the arrival of Europeans. We are using microsatellite markers and chloroplast sequencing to understand the phylogeography and population genetics of this charismatic species and to test hypotheses regarding anthropogenic post glacial maximum range expansion.
Dat T. Hoang
Dat earned his B.S. and M.S. in Biology (Thesis: Analysis of Serology and Phylogeny in Spiroplasma Classification) from Georgia Southern University. Dat is our exceptionally competent laboratory manager and technician. He keeps our lab running smoothly and contributes substantially to all of the lab's research projects.
Lura Leigh Lockard
Lura is a 3rd year Biology major at University of North Georgia. Her love of nature, science, health and food have led her to want to pursue a masters at UGA after graduating, in either the field of Plant Biology or Agriculture. She hopes to eventually improve the processes of food production for future generations.
Kirsten A. Allen
I am a Biological Sciences major with pre-pharmacy intent. I hope to obtain my Pharm.D after two years of undergraduate and four years of graduate study. Eventually I would like to work for a pharmaceutical company and pursue research in natural drugs and medicines, with a specialty in plant-based medicines.
Dan Hieu Bui
I am a 3rd year Biology major and spent my childhood in the tropical jungles of Vietnam, where I developed a passion for biology and ecology studies. In addition to working in Dr. Trapnell's research lab, I am in the Georgia Army National Guard. I want to be a biomedical laboratory technician and a U.S. Army medical officer after graduation.
Former Graduate Students
Dr. Tyler R. Kartzinel
Tyler is currently a postdoctoral research associate working with Dr. Rob Pringle in Ecology & Evolutionary Biology at Princeton University. His doctoral research at the University of Georgia focused on the influence of landscape heterogeneity and species interactions on the distribution of an epiphytic orchid and its genetic variation in Costa Rica. Tyler's current research combines manipulative field experiments with DNA-based laboratory tools to uncover processes in evolution and ecology that are rare or difficult to observe. Greater knowledge about these processes should serve to enhance both the understanding and the conservation of biodiversity. Tyler's postdoctoral research is diverse in both ecological and geographic scopes, but is principally focused on improving understanding of consequences that stem from the functional extinction of large mammals in African savannas.
