My major interests are in diagnostic and experimental lung pathology. As the lead thoracic pathologist at Yale since 2004, I have experience in diagnosing and classifying the full range of histopathology of lung disease.

I entered the MD-PhD program at Yale School of Medicine in 1979. My PhD with Donal Murphy described a novel antigenic structure within the murine MHC. Upon graduation I trained in Anatomic Pathology under the supervision of Dr. Juan Rosai and simultaneously completed a post-doctoral fellowship with Richard Flavell, chair of the section of immunobiology, with a focus on T cell tolerance. Lung specific pathology training mentors included Drs. G. J. Walker Smith, Darryl Carter and Raymond Yesner. I inherited from Dr. Smith a portion of the collection of Drs. Averill Leibow and Charles Carrington, two of the founders of modern surgical pathology of the lung.

For many years, I worked on various murine models of inflammatory lung disease, ran an NIH funded morphology core for the Yale pulmonary section and ran a laboratory at West Haven VA looking at murine models of pulmonary fibrosis. I now still consult on various experimental models of lung disease and work with collaborators analyzing human fibrotic and neoplastic disease.

I am heavily involved in medical school curriculum development as Director of Medical Studies for Pathology, am on the curriculum committee and am Co-Director of one of the new master courses for the new (starting 2015) pre-clinical curriculum for YSM.

I have been Director of Anatomic Pathology at West Haven VA since 1994.
