Education

  • PhD, Animal Science, Iowa State University, 1982

Interdisciplinary and Emerging Signature Programs

  • Other

Research Interests

  • I have built a research group and pioneered work on vascular biology changes during pregnancy with a particular emphasis on endothelial NO and angiogenesis via ATP, placental growth factors (VEG/FGF-2), and shear stress. My expertise is in uterine, fetal and placental physiology and cardiovascular function and my lab have developed numerous in vivo physiological and in vitro models centered on uteroplacental and fetoplacental vascular biology. The Magness lab has also made major models contributions and provided extensive experience in studying uterine, systemic and placental vascular modeling, and blood vessel development as it relates to placental derived steroid and angiogenic growth factor regulation of endothelial and vascular smooth muscle function.
