Clinical Expertise

Dr. Nalesnik has over 30 years of experience in transplantation pathology covering all organs and remains an active service pathologist. He has made contributions in the area of posttransplant lymphoproliferative disorders and recently headed a UNOS-based initiative to establish a systematic manner of dealing with the problem of transmission risk of organ donor-associated malignancy.

Research Expertise

Dr. Nalesnik is currently active in the area of hepatocellular carcinoma and provides ongoing support for studies related to donor organ preservation. He played an early role in defining our understanding of the range of lymphoid hyperplasias and neoplasias known collectively as posttransplant lymphoproliferative disorders.
