My research program is aimed at understanding the molecular and cellular mechanisms of early embryo development and pluripotent stem cells.  We use unique cell models and molecular cell biology tools to study cellular aging, stem cell function and cellular reprogramming / aging reversal events during early embryo development and in the generation of induced pluripotent stem cells.

Current Projects:

  • Discovering the extra-telomeric roles of telomerase reverse transcriptase (TERT) isoforms in pluripotent stem cellls
  • Deciphering the functional roles of the stress adaptor protein p66Shc in redox regulation of early embryo development and pluripotent stem cell generation/function
  • Examining the biology and utility of canine embryonic stem cells (cESCs) and induced pluripotent stem cells (ciPSCs) for clinical applications
  • Teasing apart the mechanistic roles of metabolism in regulating pluripotent stem cell state and function
  • To determine the utility of microRNAs derived from secreted exosomes as markers of developmental competence of preimplantation embryos
