Biography

Research:

My research is focused on examining the gene expression and epigenetic characteristics of early embryos produced by in vitro fertilization and somatic cell nuclear transfer (SCNT). Undergraduate students conducting research in my lab examine gene expression in early embryos using RT-qPCR.
