Current Research and Scholarly Interests I am interested in the clinical investigation of cognitive stresses during younger adulthood that may give rise to frank intellectual impairment with older age. Examples may include specific kinds of chronically taken medications.

Current Research and Scholarly Interests Studies include development and preliminary clinical evaluation of advanced techniques for ultrasonic imaging and tissue characterization. A number of studies are ongoing involving advanced techniques of magnetic resonance imaging and spectroscopy with application to the GU tract.

Current Research and Scholarly Interests My interest is in improving prostate cancer diagnosis through MRI and image-targeted prostate biopsy. In collaboration with radiologists at Stanford, we are working to define the optimal role of MRI in prostate cancer. We hope to improve cancer imaging to the point that some men with elevated PSA may safely avoid prostate biopsy. For those who need biopsy, we are evaluating novel MRI-US fusion targeted biopsy, a technique that greatly improves upon the conventional biopsy method.

Current Research and Scholarly Interests We are interested in the basic principles that govern interactions within the intestinal microbiota and between the microbiota and the host. To pursue these aims, we colonize germ-free (gnotobiotic) mice with simplified, model microbial communities, apply systems approaches (e.g. functional genomics), and use genetic tools for the host and microbes to gain mechanistic insight into emergent properties of the host-microbial super-organism.
