Qing K Li, M.D., Ph.D.

Primary Appointment in Pathology

My main research interest is to apply the advanced technology of cellular and molecular biology to the field of cytopathology, particularly in the area of early detection of lung cancers. Currently, my research is focused on: (1) detection of circulating tumor cells in non-small cell lung cancer patients; (2) identifying what molecular markers and intracellular signal transduction pathways are involved, (3) and discovering novel molecular biomarkers with early diagnostic and prognostic significance.

Identification and utilization of these molecular markers not only augment our morphologic diagnoses in difficult cases, but also provide important pathogenetic and prognostic information of lung cancers.
