Howard J. Halpern, MD, PhD, specializes in medical imaging techniques. He is an expert in very low frequency-imaging-electron paramagnetic resonance (VLF-I-EPR). This technique enables measurement of changes in oxygen content in tumor tissues--a key determinant of response to radiation therapy.
Dr. Halpern is the co-author of a textbook on free radical biology. He serves as the principal investigator for the Oversight Committee for the Laboratory Training of Radiation Oncology Residents.
