Judith Blaine, MD, PhD

Associate Professor

Medical Director, Fresenius South Denver Dialysis Unit

Dr. Blaine focuses her research on podocytes, which are key components of the kidney filtration barrier, and the damage to podocytes that leads to protein leakage in the urine and progressive kidney disease. The goals of Dr. Blaine's research are to understand two basic podocyte processes: (1) how podocytes handle serum proteins, including proteins that may modulate immune system/podocyte interactions, and (2) how podocytes communicate with one another. In understanding these processes, Dr. Blaine hopes to develop targeted therapies to protect podocytes and slow or halt both glomerular damage and progressive kidney failure.

Dr. Brosnahan has worked in clinical nephrology for over 30 years. This work began during her residency and fellowship training in Germany, where she holds an unlimited board certification in internal medicine and nephrology.  She came to the United States in 1992 for a research fellowship in Autosomal Dominant Polycystic Kidney Disease and published several original papers. After her marriage, Dr. Brosnahan repeated her training and started a professional career in America. After a few years in private nephrology practice, Dr. Brosnahan’s interest in teaching took her to the University of Arkansas, where she served as Nephrology Fellowship Director. While in this position, she worked to expand and improve the program and, in 2009, received the Nephrology Fellows Teaching Award. In July 2010, Dr. Brosnahan came back to the University of Colorado to help manage a large clinical trial in autosomal dominant polycystic kidney disease, known as the HALT PKD Trial, at the Colorado site.  She continues to work in and appreciate many diverse clinical, teaching and research activities.
