Beati, Lorenza![]()
Associate Professor of Biology and Curator of the US National Tick Collection, M.D., Ph.D., Université de Lausanne, Switzerland 1987 (2007).
- Research interests:
- I am particularly interested in studying systematic relationships among arthropod groups that are responsible for the transmission of diseases to animals and man (ticks and sand flies). Most of my work is based on molecular analyses. Ongoing projects in my laboratory include: (a) the study of the evolutionary history and phylogeography of Neotropical Amblyomma species, (b) the analysis of the genetic structure of Amblyomma cajennense, (c) the development of molecular tools for linking immature and adult tick specimens, (d) the study of population genetic of Ixodes scapularis, the vector of Lyme disease in the U.S., and (e) a revision of the phylogeny of Lutzomyia sand flies, vectors of Leishmania in South America. Ultimately, by providing tools for a finer identification and classification of arthropod vectors, my research contributes to a better understanding of the association between vectors/vertebrate hosts/pathogens – an essential step towards the development of adequate disease prevention strategies.

Claiborne, James B.![]()
Professor of Biology, Ph.D., Univ. of Miami, 1981 (1983).
- Research interests:
- We study the physiological systems involved with the regulation of salts, water and pH in aquatic organisms. We do our research on a variety of bony fish and sharks, both at GSU and during the summer at the Mount Desert Island Biological Laboratory, a marine laboratory near Bar Harbor, Maine. In a fashion analogous to the mammalian kidney, fish use their gills to transfer ions between their blood and the surrounding water. Our experiments examine these systems both in vivo and at the molecular level.
Our current NSF project focuses on the molecular and immunological detection of the RNA and protein(s) which allow these fish to excrete hydrogen in exchange for external sodium across the gills. Our laboratory was the first to demonstrate the presence of this Na+/H+ antiporter in the fish gill and we are now in the process of determining the distribution and regulation of this protein during physiological challenges to the animal. See Home Page.

Danilowicz, Bret S.![]()
Professor of Biology, Ph.D., Duke University, 1994 (2004).
- Research interests:
- My students and I work together in exploring the ecology of fishes. We generally use nested spatial scales in field sampling programs, supplemented by laboratory-based analyses, to explore the dispersal of ichthyoplankton (eggs and larvae of fish), and the consequences of this dispersal on the ecology of fish populations and assemblages. Field-based programs include collections and surveys using a combination of diving, and sampling from small and large vessels. Our laboratory-based analyses include otoliths increment analyses (for growth and age estimates), otolith composition, and enumeration of ichthyoplankton samples. Generally, my students and I use multivariate analytical and statistical techniques to infer the movement of fish, and to place their findings into the context of metapopulation biology.

Gleason, Daniel F.![]()
Professor of Biology, Ph.D., University of Houston, 1992 (1996).
- Research interests:
- My students and I combine manipulative experiments with laboratory techniques, such as HPLC, DNA fingerprinting, and allozyme electrophoresis, to address questions related to the ecology of marine invertebrates. Combining these approaches allows us to address problems at multiple scales of organization ranging from physiological to population level processes.
My research is directed into three major areas currently:
1) the role of environmental stresses, especially ultraviolet radiation, in the ecology of marine invertebrates.
2) the evolutionary and ecological importance of various reproductive modes in enhancing fertilization success and maintaining local populations in Caribbean corals and other benthic invertebrates.
3) recruitment processes of benthic marine invertebrates.
While much of my field work takes place in tropical marine systems, I am also involved in research projects along the the Georgia coast. One current local project involves studies of the benthic invertebrate fauna and recruitment processes at Gray's Reef National Marine Sanctuary. See Home Page.

Nayduch, Dana![]()
Associate Professor of Biology, Ph.D., Clemson University, 2001 (2004).
- Research interests:
- In a broad sense, I am interested in symbiotic associations between arthropods and microbes (bacteria, protozoa). My research examines the symbiosis between houseflies and bacteria for which they serve as mechanical vectors. The ultimate goal will be to elucidate factors (genetic, physiological, physical) that either promote, or deter, fly/bacteria symbioses and thereby affect overall vector potential. Current projects in my laboratory include surveys of wild-caught houseflies for pathogenic bacteria, and evaluating the role of the housefly immune system in microbial symbioses.

Bacterial pathogenesis: We are working to elucidate regulatory pathways in the swine pathogen Actinobacillus pleuropneumoniae. A. pleuropneumoniae causes a severe form of swine pleuropneumonia that has a major impact on the pork production industry.Molecular systematics: We are examining the biodiversity and biogeography of spiroplasma bacteria. Spiroplasmas are ubiquitous organisms that are often found in association with insects or plants, where they can cause diseases such as citrus stubborn or corn stunt.
Scholarship of Teaching and Learning: The Biology education research component of my program focuses on student learning in molecular biology.

- Research interests:
- My research is primarily targeted at the behavior, ecology and conservation of fishes. However, I have broad interests in interspecific interactions not targeted at a specific taxonomic group. Currently, I am studying the reproductive behavior of certain species of U.S. minnows. I am particularly interested in how species-specific behavior contributes to community patterns and to our understanding of problems in conservation biology. See Home Page.
