Thoracic disease, Research, Epidemiology, Assessment, and Treatment

Our goal is to ultimately improve the diagnosis and treatment of lung cancer for all populations. We are a multidisciplinary team of biostatisticians, nurses, thoracic surgeons and epidemiologists that perform cutting edge research in epidemiologic and clinical studies of lung cancer. We collaborate with leading investigators with expertise in genetics, epidemiology, medicine, surgery, pulmonology, bioinformatics, and health services research to improve the prevention and clinical care of lung cancer.
