RESEARCH EXPERIENCE

  • Post-doctoral Fellow - The University of Arizona, 2010 - Present
    Studied fetal programming of metabolic dysfunction related to placental insufficiency and fetal growth restriction after maternal stress. Research results showed links between placental insufficiency and life-long aberrant adrenergic regulation of muscle mass, insulin secretion, and metabolism. Developed surgical techniques for fetal adrenal demedullation and adapted protocols for myoblast isolation, primary muscle fiber metabolism, and myoblast function/metabolism for fetal/neonatal lambs after prenatal stress.
  • Research Assistant - New Mexico State University, 2007 - 2009
    Planned, organized, and conducted 14 research projects examining interactions between nutrition and stress responses in sheep, comparability of serum and salivary cortisol levels in ACTH-challenged sheep, vitamin E influence on fertility/reproduction in heat-stressed female and male rats, the luteolytic ability of a stress-related isoprostane in ovariectomized sheep, effects of hCG treatment regimens on progesterone and embryonic survival in ewes, effects of isoprostane infusion in pregnant rats, effects of isolation on stress markers in ewes and lambs, bioavailability of prozac after ruminal passage in sheep, and use of cotton gin trash as an alternative feed source for lactating goats.
    Assisted in planning, organizing, and conducting 4 other research projects examining effects of prozac on lactation patterns in sheep, effects of snakeweed toxicity on liver function in rats, and practicality of introducing exotic genetics into commercial sheep via artificial insemination.
  • Graduate Student - Angelo State University, 2005 - 2006
    Conducted 2 research projects examining effects of an alternative nutrient source (seaweed) on fertility in male goats and effects of age-specific breeding strategies on life-long fertility and reproduction in sheep.
