I direct the Buffalo Neuroimaging Analysis Center (BNAC) and have established the center as a world leader in performing quantitative MRI analysis in neurodegenerative disorders. I also direct magnetic resonance imaging (MRI) at UB’s Clinical Translational Research Center (CTRC). I strive to extend the boundaries of current knowledge about neurological diseases and disorders through innovative imaging research techniques and the application of bioinformatics resources. My efforts are directed toward advancing technical, basic and translational research at UB which will, in turn, advance patient care.
I have secured more than $25 million in research grants for collaborative research projects involving UB investigators as well as national and international collaborators. My research interests include structural and functional quantitative MRI analysis for humans and animals, including lesion/tumor identification and segmentation; perfusion and dynamic contrast-enhanced (DCE) mapping and quantification; fluid flow quantification; functional MRI analysis; diffusion tensor reconstruction and tractography; voxel-wise mapping and image-based group statistical analysis; longitudinal change analysis and tissue/pathology/structure volumetry. I study the application of these techniques in healthy individuals and in patients with various disease states such as multiple sclerosis (MS), stroke, Alzheimer’s disease, Parkinson’s disease, epilepsy, systemic lupus erythematosus and traumatic brain injury. I also concentrate on therapeutic interventions, including therapy directed toward assessing neuroprotective efforts in neurodegenerative disorders as well as the venous function, genetic and neuroepidemiology fields of these diseases.
I direct the neurology resident research program. Over a period of two years, I guide third- and fourth-year medical residents through a rigorous assigned scientific research project that is a critical, required part of their training. In addition, I mentor and supervise undergraduate, master’s and doctoral students and MRI fellows. In this role, I help to educate these trainees on clinical MRI use as well as neuroimaging analysis. I also oversee students and fellows conducting research in neurological disorders. One of the most rewarding experiences in my career is helping young physicians and researchers start successful clinical or research careers.
