Research Interests

Molecular genetics and genomics can provide a variety of tools for understanding the biology of mosquito disease transmission. Work in my laboratory has been focused principally on mosquitoes within the Stegomyia subgenus Aedes albopictus, Aedes aegypti, and Aedes polynesiensis as well as mosquitoes within the Anopheles crucians s.l. species complex. We have ongoing projects exploring mosquito genotypes associated with insecticide resistance in these mosquitoes as well as the development of genetic markers for accurate species identification.

An enhanced understanding of the genetics of these disease vectors could play a role in the identification of appropriate methods of vector control that would lead to decreased disease transmission and the alleviation of human suffering.

We also have an ongoing interest in my lab in pathogens of veterinary interest. Past projects in my lab have focused on using a reverse transcriptase polymerase chain-reaction (RT-PCR) assay in order to identify the infective stage of the filarial parasite, Dirofilaria immitis, in the mosquito vector. Current studies are employing traditional PCR in order to determine the prevalence of D. immitis infection in a variety of mosquito species found throughout South Georgia and North Florida.

Finally, we are initiating a study to investigate the epidemiology of the apicomplexan protozoal parasite, Cytauxzoon felis, in South Georgia and North Florida. Through the use of genetic markers and DNA sequencing we seek to determine if genotypic differences within this parasite exist among their hosts; hard ticks, Bobcats, and domestic cats. Such differences may be informative as we seek to understand why some domestic cats are now able to serve as infected carriers when this pathogen was once thought to be universally fatal in them.
