I am a board-certified oncologist and cancer researcher. I care for patients with all types of head and neck cancers, including esophageal, thyroid and salivary gland cancers.

Much of my work has focused on squamous cell carcinomas and cancers of the thyroid, salivary gland, and HPV-related oropharyngeal cancers. As a physician-scientist, he is especially interested in developing novel therapies and understanding mechanisms of sensitivity or resistance; cancer screening; and using medication and other agents to delay or prevent cancer (chemoprevention). Additionally, I was recently appointed chair of the National Cancer Institute Head and Neck Cancer Steering Committee, which oversees NCI-funded clinical research in this disease.
