Research Network


Dr. Katzman's primary clinical interests are in pediatric developmental and oncological diseases, and placental pathology. He is coordinator for the Antenatal and Postnatal Pediatric Pathology residency rotations.

Professional Background

I am a pediatric pathologist with a fellowship in pediatric pathology. I also have experience in clinical pediatrics and in bench research.


My research interests include diseases in placental pathology. Chronic inflammatory lesions are a particular focus, including chronic villitis. I have served as collaborator on the National Childrens' Study with our lab as the Placenta Processing Center and on the UPSIDE and ECHO projects that are underway at URMC.
