Dr. Lipschutz's research involves kidney development, how this process goes awry in polycystic kidney disease and how it contributes to the recovery that follows acute kidney injury. In his basic science lab, these questions are examined at a cellular and molecular as well as a translational level.
Dr. Lipschutz has a military background as a physician in the Pennsylvania Army National Guard with active duty deployments to both Iraq and Afghanistan. He treats men and women who seek medical care at the Philadelphia VAMC where he is also the Chief of Nephrology.

Research Interests:
- PKD and mechanisms of ciliopathy
My goal is to better understand the pathogenesis of human PKD, and lay the groundwork for the discovery of novel therapies. I'm currently studying the roles of the small GTPase Cdc42 in Renal ciliogenesis and cystogenesis using zebrafish and mouse models.

Research Interests:
- Role of ciliary signaling during organogenesis.
During my graduate studies, I focused on the role of Planar Cell Polarity (PCP)/ciliary signaling during the morphogenesis of the mouse inner ear.
Now I focus on the role of the exocyst complex in the regulation of the novel urocrine signaling pathway. Additionally, I am testing the use of adeno-associated viruses (AAV) as therapeutic agents for autosomal dominant polycystic kidney disease (ADPKD) and acute kidney injury.
