Research Training

I completed my Master’s thesis in December of 1995 at Iowa State University’s Department of Animal Science under the supervision of Dr. Steven P. Ford. The Master’s thesis title is “A comparison of preimplantation development of embryos from Chinese Meishan and Yorkshire pig breeds”. That work was set up to expand on the understanding of the mechanisms whereby the Meishan pig accomplishes increased litter size when compared to European pig breeds. Those data suggested that reduction in the number of trophectoderm cells during early embryogenesis, and not inner cell mass cells, may result in a reduced placental size and an increased litter size in prolific breeds such as the Meishan. One first-author publication and a scientific meeting abstract presentation resulted from that work.

My Ph.D. dissertation was completed in December of 2003 and was supervised by Dr. Peter J. Hansen in the Department of Animal Sciences at the University of Florida. The title of the Ph.D. dissertation is “Cellular, subcellular, and developmental responses of two-cell bovine embryos to a physiologically relevant heat shock”. The conclusions from that work were that physiologically-relevant heat shock disrupts development of two-cell embryos and this action is mediated, at least in part, by disruptions of the mitochondria and cytoskeleton. Furthermore, heat shock does not cause immediate block to development in the two-cell embryo but prevents development past the eight-cell stage. Five first-author publications and five scientific meeting abstract presentations resulted from that work.

My post-doctoral training (January 2004-July 2007) was conducted in the laboratories of Drs. Richard Schultz and Marisa Bartolomei of the Departments of Biology and Cell & Developmental Biology at the University of Pennsylvania, respectively. The studies were directed towards the understanding of how culture conditions affect the genomic imprinting pattern of mouse preimplantation embryos and post-implantation concepti. One first-author publication and two scientific meeting abstract presentations resulted from that work.
