I am a surgical pathologist with nearly twenty years of experience and expertise in Pediatric Pathology. My career began at the pediatric teaching hospital in Warsaw, Poland.

My role at Oishei Children's Hospital includes surgical sign-out service, teaching residents and fellows, lecturing in the pathology residency program and UB School of Dental Medicine, participating in interdepartmental conferences, and collaborating with Roswell Park Cancer Center. My clinical and research interests focus on pediatric gastrointestinal disorders, liver diseases, and childhood tumors. I also provide expertise in perinatal and placental pathology and pediatric and perinatal autopsy services. I actively collaborate on research projects across pediatric subspecialties at Oishei Children's Hospital.
