Biography

I am a medical oncologist who focuses on the care of patients with lymphoma, and I have clinical expertise in all types of lymphomas. My research is aimed at developing an improved understanding of new therapies for patients with several less-common types of lymphoma, including T cell lymphomas, cutaneous (skin) lymphomas, Hodgkin disease, and lymphomas in immunosuppressed patients after organ transplant (post-transplant lymphoproliferative disorders or PTLD).
