Dr. Daniel (Danny) Song is a Professor of Radiation Oncology, with joint appointments in Urology and Oncology. He serves as the Co-director of the Prostate Cancer Multidisciplinary Clinic at the Johns Hopkins Hospital and the Physician Advisor and Director of Faculty Affairs for the Department of Radiation Oncology and Molecular Radiation Sciences. His area of clinical expertise is in the management of genitourinary cancers, including cancers of the prostate, bladder and urinary tract, and testicular cancer.

Dr. Song applies his expertise and clinical experience in the utilization of a variety of radiation modalities including external beam radiation, image-guided and intensity-modulated radiation, prostate brachytherapy (seed implants), and stereotactic body radiation therapy.

Dr. Song's research interests include the development and refinement of new imaging methods to improve radiation targeting, as well as innovative means of reducing potential side effects of radiation treatment.  His research is supported by federal and private research funding programs including two R01 awards from the National Cancer Institute, Department of Defense Prostate Cancer Clinical Trial Award, the American Cancer Society, and the Hopkins-BMS Immuno-Oncology Consortium.

He is a reviewer and examiner for the American Board of Radiology, which administers the national board certification examination for radiation oncologists.   He has served on the editorial boards of the International Journal of Radiation Oncology, Biology, Physics and The Prostate, and on the scientific review committees for the American Society for Radiation Oncology (ASTRO), American Brachytherapy Society, and the Dept of Defense Prostate Cancer Research Program.  He currently serves on the Scientific Planning Committee for the American Brachytherapy Society annual meeting.  He has co-authored consensus guidelines on stereotactic body radiation therapy (TG-101) and image-guided robotic brachytherapy (TG-192) produced by the American Association of Physics in Medicine.

Dr. Song sees patients at the Johns Hopkins Hospital (downtown Baltimore) as well as Greenspring Station (Timonium) practices.
