  • Manju Prasad

    Director, Head, Neck & Endocrine Pathology

    I was born in India and am the first to go to medical school in my father's side of the family. I was 17 years old at the time, straight out of high school and was overwhelmed by my patients' desperate and immediate need for help. I realized I could remain more objective and focused if I practiced pathology and helped the treating physicians understand the underlying mechanisms of disease, so treatments could be individualized. From the start, I have been fascinated by cancer cells, their immortality and lethality. My interest is in detecting cancer, predicting their behavior and response to therapeutic agents, many of which are harmful to the patients. My current practice and work is focused on thyroid, salivary and head and neck cancers, in identifying their protein expression profiles and new targets for therapy.

  • Robert Homer

    Director, Thoracic Pathology; Director, Medical Studies

    My major interests are in diagnostic and experimental lung pathology.

    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.

    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. I have been lead thoracic pathologist at Yale since 2004.
