Charles M. Rudin, MD, PhD - MSK Thoracic Medical Oncologist

Memorial Sloan Kettering hematologic oncologist Mark Geyer specializes in caring for people with leukemia. He also studies new ways to use immunotherapy to treat leukemias.

I am a general pulmonologist. I see many outpatients with lung problems ranging from routine to esoteric conditions — not just those related to cancer. These medical issues include asthma, chronic obstructive pulmonary disease, interstitial lung disease, sarcoidosis, and many others.

I am an oncologist who specializes in treating people with multiple myeloma. The increase in new treatments in the past several years makes this a very exciting time for me and other specialists who care for people with this disease. Our team offers patients the highest-quality care as well as the newest treatments through clinical trials. These research studies will improve care and increase the chance of a good outcome for all of our patients.
