Summary

I am a board-certified medical oncologist who specializes in treating patients with lung cancer and thymic tumors (thymoma and thymic carcinoma). In addition to caring for men and women with these diseases, I work to develop new treatments by designing and conducting clinical trials. My clinical research focuses on the treatment of patients with thymic tumors as well as non-small cell lung cancer with specific mutations (EGFR, KRAS, BRAF, or EML4-ALK mutant non-small cell lung cancer).
