Professional Background

Dr. Rosenzweig is a Senior Medical Physics in the Department of Radiation Oncology at the University of Rochester Medical Center, and served as Director of Clinical Medical Physics for many years. He entered the field in 1993 as a post-doctoral fellow in the same department, having completed his graduate research in the area of experimental nuclear physics at the University of Washington in Seattle.

A native of Wisconsin, Dr. Rosenzweig served as a senior staff physicist for 8 years at St. Luke's Medical Center in his hometown of Milwaukee. He then took the opportunity to rejoin colleagues here at the URMC in a leadership position as the department undertook the major initiative of relocating to the new Wilmot Cancer Center in 2008. He is currently working in a part-time capacity, but continues to help guide the Physicist and Dosimetrist activities at the Wilmot Cancer Center and its affiliates. Guidance involves issues related to clinical operations associated with technologies surrounding linear accelerators, CT's, treatment planning equipment, and information systems.

His main area of interest is external beam radiation therapy.

Post-doctoral Training & Residency

10/1993 - 10/1995
UNIVERSITY OF ROCHESTER - POSTDOCTORAL FELLOW: Department of Radiation Oncology -- Obtained Radiation Oncology medical physics clinical training in parallel with main research assignment. Clinical experiences included participating in stereotactic radiosurgery procedures and QA, conventional radiation therapy treatment planning and procedures, periodic Linac checks and calibrations, and acceptance testing of 2-D and beta testing of 3-D treatment planning systems. The research project involved development of a miniature computer-controlled conformal collimator apparatus for treatment of intracranial lesions. Responsibility for all aspects of the device development including; hardware design, generation of control software, physical implementation, and dosimetry. -- Additional activities included: Consultations with experimental radiobiologists; Examination of the realistic effective volume of killed cells in radiosurgery procedures; Investigation of the utility of an in-house film scanner for purposes of radiosurgery beam QA and general dosimetry tasks; Studies of the correlation of CT and MR images as encountered in stereotactic radiosurgery.
