Personal Statement

Diagnostic patient care has been my focus in neoplastic and non-neoplastic pulmonary pathology. In rendering an opinion, the pathologist must go beyond diagnosis by actively participating in multidisciplinary discussions and incorporating those conclusions into a larger interpretation. In neoplastic lung disease, this largely involves matching the surgical, oncologic and imaging features with the histopathology to assure an accurate tumor classification. In non-neoplastic lung disease, the incorporation of imaging and physiology, as well as clinical presentation, is critical to providing the best patient care that pathology can provide.

The main focus of my research interest has been in the characterization of lung adenocarcinoma with an emphasis on invasion acquisition. The transition from pre-invasive precursor lesions to invasive adenocarcinoma with metastatic potential has been an area of intense examination. In the course of these studies, combining morphologic examination with whole exome sequencing, copy number analysis, gene expression profiling and laser capture microdissection has led to observations linking acquisition of invasion to gene expression differences. Prior work led to the identification of TGFBR2 loss as a critical step in the progression of early lung adenocarcinoma, culmination in a mouse model that closely resembles the human in-situ to invasive transition. This was performed in conjunction with the examination of a large cohort of lung adenocarcinoma patients in which pathologic characterization led to conclusions regarding invasive size measurement in lung adenocarcinoma. Most recently, application of NGS combined with morphologic assessment led to the finding of a high rate of actionable MET exon 14 skipping mutations in an aggressive subtype of lung carcinoma - pulmonary sarcomatoid carcinoma.

Teaching of medical students, residents, fellows and other physicians was a major reason for selecting Pathology as a career, and this remains an integral component of my academic activity. Through clear presentation, apt analogies and an ability to distill the critical teaching points from subject matter, I have been able to maintain a high level of learner satisfaction, manifested by longevity in teaching roles, positive verbal and written evaluations, and invited participation in regional and national venues.

In addition, through the New York Pathological Society, Pulmonary Pathology Society, College of American Pathologists and the American Society of Clinical Pathologists, I have used both regional and national platforms to educate pathologists about Molecular Biology with the goal of updating and re-educating practicing pathologists in an era of rapidly evolving Molecular Pathology, with a focus on lung cancer and mesothelioma.
