My current primary research focus is on enhancing scientific understanding of the role of oxidative stress in porcine oocyte maturation, fertilization, and early embryonic development. We are specifically investigating the role of a unique amide product in enhancing embryonic development following the assisted reproductive technologies of in vitro fertilization, intracytoplasmic sperm injection, and pronuclear microinjection. Other research interests and previous areas of research publications include uterine function, maternal-conceptus interrelationships during pregnancy, placental function, placental steroidogenesis, and production of transgenic swine that express human therapeutic proteins. I also have an ardent interest in the application of basic scientific knowledge to contemporary ethical, moral and philosophical issues associated with human reproduction.
