Research Summary

I am a radiation oncologist focusing on the treatment of lung cancer and head and neck cancer, working at the Yale University School of Medicine, and the Smilow Cancer Hospital at Yale New Haven. I am a member of the Cancer Center’s Radiobiology & Radiotherapy Program. For early lung cancer, my research focus is based on the treatment of stage I or II NSCLC with SBRT. For advanced cancer, my research focus has been the addition of targeted agents concurrently with fractionated radiation, in an effort to increase the tumor radiation response, and in combining radiation with immunotherapy in metastatic disease.
