The Free Radical and Radiation Biology Program provides in-depth training and research experience in the physical, chemical, and biological effects of radiation. It also focuses on the metabolic production of free radicals and their role in biology and medicine.
Free radicals are of interest to researchers and clinicians due to their role in a variety of diseases and pathological states, including degenerative diseases of aging and cancer. Manipulation of free radical reactions and redox biology holds great promise for the future development of new therapies for a variety of human diseases. The Free Radical and Radiation Biology Program stresses the importance of these areas of research to basic science, translational research, and public health.
Three courses offered by the Free Radical and Radiation Biology Program are open to University of Iowa undergraduate students: FRRB:3130 Radiation Safety and Radiobiology, FRRB:4000 Special Topics: Advanced Undergraduates, and with instructor approval, FRRB:5000 Radiation Biology. Students looking for an overview of the biological effects of radiation, including the role of free radicals, will find FRRB:5000 especially appropriate.
Postdoctoral training is available by arrangement with the program's director and individual faculty members. Contact the Free Radical and Radiation Biology Program.
Graduate Programs of Study
- Master of Science in Free Radical and Radiation Biology
- Doctor of Philosophy in Free Radical and Radiation Biology
Students interested in doctoral studies in free radical and radiation biology should apply under the newly created umbrella program in Biomedical Science (select free radical and radiation biology subprogram). Direct applications to the M.S. and Ph.D. in free radical and radiation biology are not currently being considered. Students who entered a graduate free radical and radiation biology program prior to fall 2017 can refer to the 2015-16 General Catalog for previous degree requirements.
The Free Radical and Radiation Biology Program is the home of the Radiation and Free Radical Research Core Lab (RFRRC). The lab operates a 300 kVp orthovoltage X-ray generator and other radiation sources, including an 8,000-Curie Cs-137 irradiator (Ionizing Radiation Services). Students and staff have access to additional core lab support through RFRRC, with services and expertise related to analytical chemistry (Electron Paramagnetic Resonance services) and redox biology, biochemistry (Antioxidant Enzyme Services), and linear accelerators in the Department of Radiation Oncology.
The program has a number of radiation detectors and counters, including liquid scintillation counters. It also has ultraviolet/visible spectrophotometers; various types of equipment for densitometry, chromatography, and electrophoresis; modern tissue culture facilities; seahorse metabolic profiling instruments; molecular biology equipment, including thermal cyclers; an automatic cell counter and particle sizer; tissue culture facilities; Typhoon phosphorimager; high-performance liquid chromatography (HPLC); electron spin resonance spectrometers; and nitric oxide analyzers.
