Research Summary

My research focuses upon the reproductive biology of insect vectors of human disease. My Ph.D. thesis in the lab of Dr. Alex Raikhel, is focused upon the effects of nutritional components of blood (amino acids) upon the transcriptional regulation of yolk protein genes in the Yellow Fever mosquito (Aedes aegypti). My current work in the Aksoy lab involves the molecular characterization of reproductive processes of the viviparous Tsetse fly (Glossina morsitans morsitans). This work targets multiple aspects of reproduction in tsetse including nutrient metabolism and mobilization to the intrauterine offspring; identification and characterization of reproductive genes and regulatory mechanisms; and the role of the obligatory symbiotic bacteria wigglesworthia in tsetse fertility.
