Pryce Haddix
Associate Professor | College of Sciences
Ph.D. Microbiology, May 1992, University of Kentucky
B.A. Biology with chemistry emphasis, May 1985, Transylvania University, Lexington, KY
Dr. Haddix is an Associate Professor in the Biology Department in the School of Sciences. He has a broad background in microbiology and molecular biology. His research interests are in the biological functions of bacterial pigments and the use of bacteria as biological sensors for the detection of environmental contaminants.
Dr. Haddix’s primary research interest involves identifying and characterizing the biological function of a red pigment made by the soil bacterium and opportunistic bacterial pathogen Serratia marcescens. His early work on this project built a circumstantial case for a negative role for prodigiosin pigment in cellular energy production during high-rate cell multiplication when cellular energy levels begin at their maximum (PubMed ID # 18805986). More recent work has revealed that the pigment has a positive function in cellular energy production when cellular energy levels are low; this positive function ultimately produces a doubling of pigmented cell yield over that of non-pigmented cells (PMID # 29616306). His most recent work has more clearly defined the negative role, and a manuscript describing these results is due to be submitted for publication in spring, 2019. Ongoing experimental work will more closely address the positive function and build a model for prodigiosin pigment in the cellular energy fluxes associated with Serratia marcescens population growth.
Vanessa Koelling
Assistant Professor | College of Sciences
Ph.D. University of Georgia (2008), Genetics
B.A. Reed College (2000), Biology
Bio: Dr. Vanessa Koelling is an Assistant Professor in the Department of Biology and Environmental Science. She is a plant evolutionary biologist, which means that she studies how plant populations change over time in response to new environmental conditions. Within the field of evolutionary biology, she is particularly interested in the evolution of plant mating systems, the mechanisms of plant speciation, and in plant evolutionary genetics. Her work aims to understand which evolutionary mechanisms are most important in plant mating system evolution and speciation, and to understand the causal genetic changes underlying plant adaptations. She currently studies these topics using the common yellow monkeyflower (Mimulus guttatus), a wildflower endemic to the Western United States with many features that make it an ideal system for the study of evolution. She has also begun a new project to study the population genetics, ecophysiology, and evolution of two of Alabama’s native azaleas (Rhododendron cumberlandense and Rhododendron prunifolium). In addition, she is interested in eventually expanding her research into other Southeastern plants.
Dr. Koelling has published her work in distinguished scientific journals, such as Heredity, the American Journal of Botany, and The American Naturalist. She is a member of the Society for the Study of Evolution and the Botanical Society of America. (Scholar page)
Dr. Koelling is also an experienced teacher who has taught a range of introductory and specialized courses. She especially enjoys teaching topics in evolution, genetics, and applied bioinformatics. She incorporates inquiry-based and active-learning methods into her courses, and continually seeks new ways to engage and motivate students in her classrooms.
