Mara Schvarzstein's Web site
Mara Schvarzstein obtained her Ph.D. at the University of Toronto in the Department of Molecular Genetics, where she investigated mechanisms of sexual fate specification and gonadogenesis using the C. elegans model organism. She continued her interest in sexual reproduction during her postdoctorate at Stanford University in the Department of Developmental Biology. At Stanford, she used C. elegans to investigate the regulation of several key steps in meiosis that are critical for accurate chromosome inheritance in oocytes, spermatocytes and the zygote. Schvarzstein arrived at Brooklyn College in 2014. The Schvarzstein lab focuses on uncovering mechanisms promoting accurate chromosome and centrosome inheritance in meiosis, and importantly, the consequences when errors in these mechanisms arise.
