Research Interest
My research focuses on the development of software tools and strategies for modeling human neural systems, emphasizing detection of disease-related and treatment-induced alterations in inter-regional connectivity.
I am NIH funded to develop tools for coordinate-based meta-analysis of the neuroimaging literature, with the goal of developing “starting models” which serve to improve model fit and enhance the discriminant power of the models. I am DOD funded to apply these imaging/modeling strategies to study post-traumatic stress disorder. RII web link

Kenneth A. Kist, MD

Associate Professor/Clinical


Research Interest
My primary interests lie in improving the efficiency and acceptability of breast imaging and related procedures. In addition, I am interested in the perceived barriers to breast imaging and techniques to lower or eliminate these impediments.

William T. Phillips, MD

Clinical Professor

Research Interest
I am a Nuclear Medicine physician with research interests in translational and clinical medicine. In translation research, I have had a long interest in nanoparticle drug delivery and have developed new ways to label nanoparticles with diagnostic and therapeutic radionuclides. Imaging of nanoparticles has lead to the development of novel nanoparticle-based methods of delivery drugs. Nanoparticles composed of lipids, known as liposomes, have been my greatest focus. In clinical research, I have had a long interest in gastric emptying as investigated with the gold standard technique of nuclear imaging. I have found that the rate of gastric emptying is an important controlling factor for postprandial glucose levels and that patients with type 2 diabetes and hypertension frequently have excessive rapid gastric emptying.
