Biography

My research has focused on the control of different aspects of the meiotic cell cycle and control of meiosis in general. We have primarily used mouse spermatogenesis as a model; however, different lines of research have been done using yeast and Drosophila meiosis models. Currently, my interests are in graduate education and training and scientific outreach to undergrads, high school students, and high school teachers.

At the graduate level, I am involved in promoting scientific excellence and integrity, graduate student recruitment, and student affairs. In the undergraduate realm, my goals are to increase awareness of science as a career opportunity and help prepare undergrads for their graduate school careers.

Concerning pre-college outreach, I am interesting in increasing the science awareness and aptitude of middle- and high-school students, providing mentoring and research opportunities for those students, and providing resources to teachers to reach these goals.
