My research activities have centered on the molecular mechanisms of neoplastic transformation. My specific interest in cardiovascular-respiratory pathology has focused on the molecular pathways involved in the development and progression of neoplasms of the lung and head and neck. Our work has identified the earliest morphologic stages of lung tumorigenesis (i.e. adenocarcinoma in situ), and the molecular mechanisms driving the early stages and progression of carcinomas of the lung and head and neck. A particular emphasis of this work has been the utilization of specific genetic alterations as a novel means of early cancer detection and tumor surveillance.
