Research Interests

Our lab is interested to better understand processes affecting puberty, fertility, and human development. With an emphasis on translational medicine, we hope to identify genes important for the development of normal puberty, sexual differentiation, and other organs including the heart and brain. In addition we want to optimize the outcome for patients with infertility, pregnancy loss, and assisted reproductive technologies, as well as reducing the likelihood of birth defects. Most recently, we received NIH grant funding for a project to identify genes involved in uterine and vaginal development.

Current Projects

  • Identifying gene mutations in patients with absent puberty due to hypothalamic-pituitary disorders (hypogonadotropic hypogonadism and Kallmann syndrome)
  • Mouse models of infertility
  • Mapping causative genes in patients having an underdeveloped uterus and vagina
  • Study of genes involved in sex determination and differentiation
