    Margaret T. Fuller

    Reed-Hodgson Professor in Human Biology and Professor of Genetics and of Obstetrics/Gynecology (Reproductive and Stem Cell Biology)

    Current Research and Scholarly Interests Regulation of self-renewal, proliferation and differentiation in adult stem cell lineages. Developmental tumor suppressor mechanisms and regulation of the switch from proliferation to differentiation. Cell type specific transcription machinery and regulation of cell differentiation. Developmental regulation of cell cycle progression during male meiosis.

    Aaron Hsueh

    Professor of Obstetrics and Gynecology (Reproductive and Stem Cell Biology), Emeritus

    Current Research and Scholarly Interests Hormonal regulation of ovarian function; gonadotropin receptors and related genes, bioinformatic ananlyses of polypeptide hormones and receptors, follicle recruitment and GDF-9; analysis of oocyte and ovarian-expressed genes.

  • Roberta Sala

    Roberta Sala

    Instructor, Obstetrics & Gynecology - Reproductive Biology

    Current Research and Scholarly Interests I am a cell and molecular biologist by training. During my PhD I worked on the identification of thymidine kinase 1 phosphorylation status during cell cycle progression and its relevance for PET imaging of cell proliferation. In the Stearns lab I was interested in how cells cope with multiple centrosomes and what are the mechanisms ensuring centrosome number homeostasis. In the Sebastiano lab I am studying germ cell differentiation and what are the cell biological effects of de-differentiation.

  • Vittorio Sebastiano

    Vittorio Sebastiano

    Assistant Professor (Research) of Obstetrics and Gynecology (Reproductive and Stem Cell Biology)

    Current Research and Scholarly Interests The thread of Ariadne that connects germ cells, preimplatation development and pluripotent stem cells is the focus of my research, with a specific interest in human development. My long-term goals are: 1. Understanding the biology of germ cells and and their ability to sustain early preimplantation development; 2. Understanding the mechanisms that regulate very early cell fate decisions in human embryos; 3. Understanding the biology of derivation and maintenance of Pluripotent Stem Cells

  • Virginia Winn

    Virginia Winn

    Associate Professor of Obstetrics and Gynecology (Reproductive and Stem Cell Biology)

    Current Research and Scholarly Interests The Winn Laboratory seeks to understand the unique aspects of human placental biology that contribute to pregnancy complications. Abnormalities in placental biology lead to more than 25% of pregnancy complications that impact the health of mothers and their babies. The primary focus of Dr. Winn's lab is to understand human placentation and preeclampsia pathogenesis. Both basic science and translational approaches are undertaken.
