Our Residents & Fellows

Memorial Sloan Kettering's radiation oncology residents and fellows.

Our residents come from diverse educational and personal backgrounds, but all share a passion for radiation oncology clinical practice and research. We are also fortunate to have two fellows as part of our department, specializing in brachytherapy and genitourinary (GU) radiation oncology.

We work and learn together — in a single residents’ room — and consider the camaraderie of the residents and fellows one of the major strengths of our residency program.

First-Year Residents (July 2016-July 2020)

Thomas Beckham, MD, PhD

I grew up in Aiken, SC where I discovered my interest in science and the natural world.  I developed an interest in scientific research particularly as it can be applied to improve human health during my undergraduate studies in Genetics at Clemson University.  I found an amazing training environment as a physician scientist in the Medical University of South Carolina’s Medical Scientist Training Program.  There I completed my MD training and my doctoral research in oncogenic sphingolipid signaling in prostate cancer.  I completed my internship in the Transitional Year program at Memorial Sloan Kettering Cancer Center where I learned a great deal about clinical medicine as well as the unique challenges and rewards of caring for cancer patients. I am excited to be able to continue my training in the Department of Radiation Oncology.
