Dr. Ohori has a long-standing interest in thoracic pathology including lung transplantation, but has focused his more recent energies on thoracic cytopathology in his role of Director of Cytopathology at UPMC Presbyterian. Dr. Ohori has a special interest in integrating cytopathological abnormalities with surgical pulmonary pathology, and has collaborated closely with Jennifer Hunt, MD in the utilization of molecular techniques for refining cytopathology analysis.
Sanja Dacic, MD, PhD
Dr. Dacic has a special interest in utilizing molecular techniques in the evaluation of thoracic and mediastinal (primarily thymic) neoplasia. Her interests revolve around utilizing molecular techniques on formalin-fixed paraffin embedded tissue to address problems in thoracic pathology such as epithelial mesenchymal interactions, biphasic neoplasms, molecular predictors of clinical behavior, and segregation of primary from secondary thoracic neoplasms. She has an active research program in fluorescence in situ hybridization and array based comparative genome hybridization with a focus in establishing prognostic markers of lung neoplasia.
Humberto Trejo Bittar, MD
Dr. Trejo Bittar is focused on non-neoplastic lung diseases with emphasis on the pathology of small airway diseases. He participates in many NIH funded research projects on the pathology of asthma, with particular interest in the histopathologic findings of severe asthma and the role of the immune cells. Additionally, Dr. Trejo Bittar participates in research projects developing new immunohistochemical and molecular studies for the diagnosis of lung cancer. Dr. Trejo Bittar is also interested in studying the use of digital pathology for the assessment of protein expression and the quantitative counting of inflammatory cells by immunohistochemistry. He is a member of the College of American Pathologists Histotechnology committee, in which he is involved in developing tools for the quality improvement of histologic preparations and the implementation of whole slide imaging for pathologic diagnosis. Dr. Trejo Bittar teaches many courses for the University Of Pittsburgh School Of Medicine and he is a member of the University of Pittsburgh School of Medicine Admissions Committee.
