Cathy Mendelsohn, PhD, is Principal Investigator of Project Two. She is the Michael and Stella Chernow Professor of Urological Sciences (in Urology) and Pathology and Cell Biology and Genetics and Development (in the Institute of Human Nutrition, Columbia University). In addition, Dr. Mendelsohn is a member of the Endocrinology Training grant, the Departments of Urology, Genetics & Development, the Columbia Stem Cell initiative, and the Nutrition program. 

Dr. Mendelsohn obtained a BS in Microbiology from the University of Massachusetts at Amherst and a PhD in Microbiology at Columbia University Medical Center, cloning the human Poliovirus receptor working with Dr. Vincent Racaniello’s lab. Her postdoctoral studies in Pierre Chambon’s lab, at the Université Louis Pasteur, in Strasbourg, France, were focused on Retinoic Acid Receptors and their role in development, which she continued in the lab of Jane Dodd at Columbia University. She initially evaluated retinoid signaling in kidney development, but in the past decade has identified the basis of urogenital anatomy and urothelial function.
