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.
