Dr. Obenaus serves as the Director of the Non-Invasive Imaging Laboratory in the Radiation Biology Program at Loma Linda University. His laboratory is well known for its state-of-the-art equipment. His expertise is in the area of neuroimaging of disease, and the Noninvasive Imaging Laboratory has experience with a broad range of topics and models of disease including Alzhiemers and neurorepair using stem cells. He has been involved in teaching Biomedical Imaging and Radiation Biology, and he has supervised a number of undergraduate and graduate students.
