Research Interests

  • My research interest is in the prognostic/risk stratification in head and neck carcinomas. I am particularly interested in the utilization of epigenetic/genetic changes to predict metastatic potential or treatment response. I am also interested in clinical trials that can answer pertinent clinical questions. Furthermore the conduct of these trials confers excellent opportunities to execute correlation translational studies to address gaps of knowledge that often exists between advances in bench top science and bed side experience. Last but not least, I am an early adaptor of new surgical techniques or devices that may improve the surgical outcome of Head and Neck patients.
