Degrees: B.S. - Wildlife Ecology and Conservation – University of Florida, May 2000

Research Interests:
My research interests lie in elucidating the effects of environmental compounds on alligator phallic development. Currently, I am documenting the developmental differences during embryological growth of external genitalia in alligators reared at both male and female incubation temperatures. Proposed endpoints include morphometrics at the cellular and tissue levels and steroid receptor prevalence in tissues from animals of different ages. I plan to use this information in researching potential variation in alligators from contaminated and reference lakes in Florida. Ultimately, I’d like to identify to what degree, if any, reproductive anomalies in wildlife (and their causes) can be paralleled with those of humans (i.e., cryptorchidism, hypospadias, decreased sperm count, etc.). Additionally, I am studying alligator eggshell variation within and between different Florida lakes.
