Professional Focus

Dr. Daftari is a primary physicist responsible for treatment planning, treatment delivery, safety and quality assurance and supervision of proton beam therapy of ocular tumors.  He was instrumental in setting a program for proton beam therapy treatment of ocular melanoma.  This UCSF program was initiated at Crocker nuclear Laboratory, University of California, Davis cyclotron in 1994.  It was an outgrowth of research performed at Lawrence Berkeley National Laboratory.

Dr. Daftari has been involved in numerous research projects including topics in experimental high-energy physics, conventional and charged particle therapy and Image-guided radiation therapy.  His research interests include both topics in conventional and proton beam dosimetry, planning and image guided radiation therapy.
