Zachary S. Buchwald, MD, PhD, is Assistant Professor in the Department of Radiation Oncology at Emory University School of Medicine. Dr. Buchwald's primary clinical focus is radiation and immunotherapy for cutaneous malignancies.


Dr. Buchwald completed his PhD in Immunology and his MD in Medicine at St. Louis University in St. Louis, Missouri. He completed his residency in Radiation Oncology at Emory University School of Medicine in Atlanta, Georgia serving as co-chief resident in his final year. During residency, Dr. Buchwald completed a prestigious research fellowship, the Holman Pathway.


Dr. Buchwald is actively involved in both basic and clinical research. In his laboratory, he studies ways to enhance the immune response against melanoma and other cancers using radiation. He is working to understand how different T-cell subsets are stimulated by radiation, the role of the tumor-draining lymph node in this process, and how to enhance this process with the goal of controlling disease in patients with locally advanced or metastatic cancer. Additionally, he studies ways to overcome steroid induced immuno-suppression of the anti-cancer immune response using focal, high dose radiation and combination checkpoint blockade. His lab is also focused on using radiation to modulate the immune response to viral infections and inflammatory diseases. He plans to continue translating these laboratory studies into clinical trials with the goal of improving long-term patient outcomes.
