I am passionate about mathematical modeling in general, but my research interests focus on computational neuroscience and image analysis. Specifically, I use computational modeling to study cellular mechanisms underlying working memory, and how those mechanisms are affected by aging and neurodegenerative disease. The models are constrained by morphologic and electrophysiological data collected by my colleagues at Boston University School of Medicine and the Icahn School of Medicine at Mount Sinai (New York, NY), resulting in multidisciplinary studies that demonstrate a unique approach to research. This requires methods for automated parameter optimization, a research area that we actively pursue. An intriguing outcome of our research is the application of sensitivity analysis approaches, to predict which electrical parameters to change, and by how much, will to compensate for a given age-, disease-, or development-related morphologic change, to restore normal function. We are extending these methods in new directions, and applying them to our current modeling problems to help us elucidate the mechanisms that shape neuronal function.
