With years of experience, he is board-certified in radiation oncology by the American Board of Radiology (ABR). The mission of the ABR is to serve patients, the public, and the medical profession by certifying that its diplomates have acquired, demonstrated, and maintained a requisite standard of knowledge, skill, and understanding essential to the safe and competent practice of diagnostic radiology, radiation oncology, and medical physics.

For nearly 10 years, Dr. Barani was on faculty in the Radiation Oncology Department at the University of California-San Francisco (UCSF). He served there as vice-chair and director of clinical research from 2010 until 2015. 

His current research studies explore various applications of big data analytics and artificial intelligence with the aim of improving outcomes for brain tumor patients and making clinical workflows more efficient. As a co-investigator at the Ivy Brain Tumor Center, Dr. Barani is a key member of the Phase 0 clinical trials team and an experienced early-phase clinical trialist in neuro-oncology.

Among his professional affiliations, he is an active member of the American Society of Clinical Oncology, the American Society for Radiation Oncology, the Radiological Society of North America, and the Society for Neuro-Oncology.

Radiation oncology is a medical specialty that involves the controlled use of radiation to treat cancer. It is one of the three primary specialties, the other two being surgical and medical oncology, involved in the treatment of cancer. A radiation oncologist is a specialist physician who uses ionizing radiation in the treatment of cancer.
