About Rob Hobbs
Primary Academic Title
Associate Professor of Radiation Oncology and Molecular Radiation Sciences
Background
Dr. Robert Hobbs is an Assistant Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science and a member of the Johns Hopkins Kimmel Cancer Center. His research focuses on clinical and alpha dosimetry, modeling, and external beam radiation.
Dr. Hobbs is a member of the Radionuclide Therapy and Dosimetry (RTD) Research Lab, where he performs tail vein injections and bio-distribution, and provides assistance to Dr. Hong Song. He is engaged in research that examines how tumor burden and prior chemotherapy affects bone marrow dosimetry.
Dr. Hobbs earned his Ph.D. in experimental high-energy physics from the University of New Mexico. Dr. Hobbs joined the Johns Hopkins faculty in 2006.

Research Interests
alpha-particle therapy and dosimetry, combination therapies with radiation, radiopharmaceutical dosimetry and treatment planning
Research Summary
Dr. Hobbs' research focuses on dosimetry, which measures and calculates the radiation dose received by matter and tissue that has been exposed to radiation.
His current studies examine various radiobiologic modeling techniques for treatment of specific tumors and cancers. Dr. Hobbs is also developing an alpha-particle dosimetry model that can examines alpha particles which are hard to study with current imaging modalities.
As part of his medical physics residency, Dr. Hobbs is studying the use and effectiveness of external beam radiation.
