CRE family reunion at the Biology of Spermatozoa meeting in England

Many current and past CRE members – including Yasir Ahmed-Braimah, Steve Dorus, Brian Gress, Stefan Lüpold, Mollie Manier, Caitlin McDonough, Scott Pitnick, Nalini Puniamoorthy and Emma Whittington – meet up at the 14th biennal Biology of Spermatozoa conference in Bakewell, England, near the Peaks District. Graduate students Caitlin McDonough and Emma Whittington gave two of the best talks at the conference. BoS is very posh yet riotous fun, and easily the most intellectually stimulating meeting we attend.

New NIH Award to the CRE!

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.

CRE Postdoctoral Fellowship available!

A Postdoctoral Fellowship is available for our NSF-funded investigation of sperm modification within the female reproductive tract. Molecular interactions between sperm and the female reproductive tract evolve across closely related species and may contribute to reproductive isolation. Sperm undergo numerous modifications as they move through the male and female reproductive tracts, although the nature of these interactions and their importance for fertilization success is not well understood. This project will characterize these changes at the molecular level, within closely-related species of fruit fly, as well as following hybrid inseminations, to understand their evolutionary history and influence on sperm survival and fertilization success.

National Science Foundation gives the CRE an anxiously-awaited thumbs up

Our research proposal to use proteomics to investigate sperm modification within the female reproductive tract, along with its evolutionary divergence and reproductive isolation consequences, is recommended for funding by the NSF. 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 and Tim Karr of the Kyoto Institute of Technology.

Brian Gress, PhD student extraordinaire, successfully defends his dissertation!

Brian’s research combined investigations from the field, laboratory and artificial pastures in the greenhouse on the LSC rooftop to explore the evolutionary maintenance of alternative male reproductive tactics in the yellow dung fly, Scathophaga stercoararia. We wish Brian great success as he begins a killer postdoctoral fellowship at UC, Davis with Frank Zalom of the Department of Entomology and Nematology.
