Research Interests
Our lab seeks to uncover genes involved in the late-stage maturation of spermatozoa in Drosophila.  Specifically, since sperm in all animal species occurs within a common cytoplasm, all animals have to resolve individual sperm from this cytoplasm in a process known as spermatid individualization. Indeed, a failure to individualize sperm is the predominant cause of male infertility in humans. Given the genetic similarity (65–70 percent) between Drosophila and humans, we hope our work will shed some light on the molecular mechanisms behind human male fertility.

External Research Support
Dr. Fabrizio received a National Institutes of Health grant for $200,000 as principal investigator. He will be incorporating methods and knowledge of genetics, molecular biology, cell biology, and genomics to study sperm development in the fruit fly, or Drosophila melanogaster.
