Winifred Mak MD, PhD

Assistant Professor of Obstetrics, Gynecology, and Reproductive Sciences; Director, Early Recurrent Pregnancy Loss Program

Research Interests

Embryogenesis; Epigenetic regulation of placental development; Role of Pumilio; RNA binding protein in oogenesis and embryogenesis; Trophoblast stem cells


Research Summary

Dr Mak, is currently one of a few physician-scientists appointed by the NIH as a WRHR (Women's Reproductive Health Research) scholar. She is presently carrying out her postdoctoral research under the supervision of Dr Haifan Lin, the director of the Yale Stem Cell Center. Her current projects include investigating the role of an RNA binding protein, Pumilio in the ovary and during embryonic development using a transgenic knockout model; the epigenetic regulation of trophoblast stem cells and their future potential use in placental therapy.
