Research Focus

Dr. Peng’s primary research focuses on female reproduction and women’s reproductive health. Her lab uses a variety tools in cell and molecular biology, biochemistry, physiology, and bioinformatics to investigate how growth factors, hormones, and microRNAs regulate oocyte maturation and placental development and how their dysregulation contribute to the pathogenesis of preeclampsia. In addition, her lab studies the molecular mechanisms underlying the development of ovarian cancer.

Current research projects in Dr. Peng’s lab include: 1) MicroRNAs and Growth Factors in Placental Development and Preeclampsia; 2) Role of Cyclin G2 and MicroRNAs in Ovarian Cancer Development; and 3) Regulation of Zebrafish Ovarian Development and Oocyte Maturation. Her work is supported by CIHR, NSERC, CFI/ORF, and York University.
