Our physics division chief, Alfredo Siochi, Ph. D., teaches a one-year clinical physics course. The one semester radiobiology course his co-directed by Dr. Todd Tenenholz, M.D., Ph.D., and Dr. Elena Pugacheva, Ph.D. Residents are given dedicated time away from clinical responsibilities for these courses. The program provides all necessary experience in stereotactic radiotherapy, brachytherapy (GYN- HDR, Prostate LDR and HDR), as well as unsealed source administration (I-125, Y-90 sir-spheres) through our nuclear medicine and interventional radiology departments. Residents also participate in one-month pediatric experience at St. Jude's research hospital in Memphis, under the guidance of Dr. Tom Merchant.
