Research Focus

Ovarian function - MicroRNA mediated post-transcriptional gene – Vesicle meditated (exosome/microvesicle) cellular communication

Research Description

Fertility control is a major health concern for premenopausal women. Research in my laboratory focuses on understanding the terminal events involved in follicular development, ovulation and luteal tissue formation.  The studies have direct implications in development of a fertile healthy oocyte, contraception and disease conditions such as polycystic ovarian syndrome and ovarian cancer.  Current studies focus on understanding the role of microRNA post-transcriptional gene regulation plays in the ovulatory process. The laboratory is also working to understand what role extracellular vesicles (exosomes and microvesicles) play in ovarian function (oocyte maturation, granulosa cell function) and in ovarian cancer.  These studies use the latest state of the art technologies, including next-gen-sequencing, nanoparticle analysis in addition to standard molecular and biochemical techniques.  The laboratory also uses a comparative approach using human, bovine and murine cells and animal studies in both cows and mice to gain further insights into the reproductive biology of the ovary.
