About John R. Subjeck


Dr. John R. Subjeck joined the staff of Roswell Park Comprehensive Cancer Center (Roswell Park) in 1979, as a Cancer Research Scientist, Division of Radiation Biology, Department of Radiation Medicine. He was appointed Member in the Departments of Cell Stress Biology and Molecular and Cellular Biology in 1999, and was also a Professor of the Molecular & Cellular Biophysics and Biochemistry Roswell Park Graduate Division, University at Buffalo (UB).

Dr. Subjeck earned his doctoral degree in Biophysical Sciences, UB School of Medicine & Biomedical Sciences in 1974. He completed a postdoctoral fellowship in Experimental Pathology at Roswell Park in 1977. From 1977-1979, Dr. Subjeck specialized in Hyperthermia as a Research Affiliate in Medical Physics in the Division of Radiation Biology at Roswell Park. He was certified by the American Board of Radiology in Therapeutic Radiological Physics. He currently serves as a Professor Emeritus, and although retired, he currently collaborates with colleagues both at Roswell Park and at the Virginia Commonwealth University.
