John Grecula, MD, is a professor in the Department of Radiation Oncology at Ohio State and a member of the OSUCCC – James Translational Therapeutics Program, where he focuses his research on radiation oncology.

Recently, he contributed to a study that showed how a focally-directed treatment strategy using fractionated stereotactic radiotherapy with or without surgery appears to be an effective initial strategy for patients with newly diagnosed brain metastases. His other recent research includes an exploration of the effectiveness of radiation therapy combined with intracerebral administration of carboplatin for brain-tumor treatment.

He has served as a principal investigator and co-investigator on more than 50 research projects, including phase I and II clinical trials.

In addition, Dr. Grecula has authored over 50 articles appearing in well-respected publications, including Magnetic Resonance Imaging, Neurosurgery, Journal of Clinical Neuroscience, Radiation Oncology and Journal of Cancer Science & Therapy.
