My research focuses primarily on reproductive physiology. Projects are directed to expand our knowledge of regulation of ovarian function as it relates to estrous cycle length and maintenance of early pregnancy. An additional interest is developing an appropriate animal model for investigation of differential gene expression in ovarian cancer. Lastly, we have projects designed to identify the mechanism(s) by which exposure to environmental estrogens can lead to infertility in males. We also have an applied aspect to our research. Projects relating to more practical applications include storage of sperm at ambient temperature, and developing reversible contraception in pet and wild animal populations.
