Personal Statement

I am an Associate Professor of Clinical Pathology and Laboratory Medicine with a focused interest in cytopathology, cytomorphologic-molecular correlation, and the integration of cytopathology with molecular oncology. My clinical and academic work centers on optimizing the use of cytologic specimens to achieve accurate, timely, and clinically meaningful diagnoses, particularly in settings where sample material is limited. I am especially interested in innovative approaches that expand the diagnostic utility of these specimens, including the application of molecular testing to cytologic preparations and supernatant-derived nucleic acids. My work in molecular genetics extends beyond molecular diagnostics to prediction of cancer patients’ responses to therapy, including immune-based approaches such as immune checkpoint blockade. I am also deeply committed to education and mentorship. I work closely with trainees to develop their diagnostic skills, critical thinking, and confidence in navigating an increasingly complex laboratory environment. Fostering the next generation of pathologists and supporting their professional growth is central to my academic mission.
