Biography

Mary Wallingford was trained in the field of embryonic development in the Mager Lab at the University of Massachusetts Amherst. Her doctoral research evaluated roles of the transcription factor and epigenetic regulator YY1 in early embryogenesis, including preimplantation, peri-implantation, and gastrulation stages. Her postdoctoral research in the Giachelli Lab at the University of Washington investigated the role of phosphate transporters in vascular development and disease at blood tissue barriers. She identified a novel cause of Slc20a2-linked neurovascular calcification and built an independent research program in phosphate transport biology of the maternal-fetal intferface. This work was supported in part by a trainee appointment in the NHLBI funded UW Cardiovascular Training Grant Program (PI: D. Dichek, T32HL007828) and by a K99/R00 Pathway to Independence Award from the NICHD (PI: M. Wallingford, K99HD090198). Dr. Wallingford’s current research brings the fields of embryology and vascular disease together to focus on development and pathophysiology of the least understood human organ: the placenta.

NIH/NHLBI T32HL007828 Cardiovascular Training Grant Program 2013-2016 University of Washington School of Medicine The Role of Phosphate Transporters in Cardiovascular Development and Disease in the Mouse. The major goal of this project was to determine the role of phosphate transporters Slc20a1 and Slc20a2 in vascular calcification mechanisms at blood tissue barriers, including cerebral vessels (blood brain barrier) and extraembryonic tissues (blood placenta barrier). Role: Trainee, Mentored by David Dichek (UW Cardiology) and Cecilia Giachelli (UW Bioengineering)

Research Focus

The research focus in the Wallingford Lab is development and pathophysiology of the placenta. The placenta contains highly specialized vasculature that mediates interaction between maternal and fetal circulatory systems during pregnancy. Impaired placental growth or function can have dire impact on maternal and fetal health. In the long-term, Dr. Wallingford aims to advance knowledge of placental development and assist in the development of early diagnostics and novel therapeutics for disorders of placental insufficiency or dysfunction. Specific areas of interest include maternal-fetal phosphate transport biology, morphogenetic analysis of placentation, and development of new approaches to assess vascular structure and function at the maternal-fetal interface.
