He also has special interests in clinical laboratory administration and pathology informatics and has published and lectured nationally on both topics

He was instrumental in discovering a new type of lymphoma (primary effusion lymphoma) common in HIV-infected patients. His more recent interests and publications deal with laboratory administration, the pathology workforce, and pathology resident education. His publications (original research, reviews, books, chapters, and abstracts) currently total 124, and he has also published 9 computer programs.
