Our research proposal to use proteomics to investigate sperm modification within the female reproductive tract of Drosophila melanogaster was just funded by an R21 grant from the National Institutes of Health (Male Reproductive Health Program, Fertility and Infertility Branch). This project complements the evolutionary research funded by our recent NSF, which explores evolutionary divergence and reproductive isolation consequences of these sperm-female interactions. This work is a collaboration between CRE members Steve Dorus, Scott Pitnick, John Belote and PhD student Emma Whittington, along with Mariana Wolfner of Cornell University. We will soon be searching for a Postdoctoral Fellow to join this research program. Please contact us if you are interested.
