With Carnegie Mellon University: investigates molecular, cellular and computational properties of brain networks with focus on mouse olfactory system; focuses on describing how biological properties of cells and their connections contribute to information processing; work often relies on construction of models that provide insight into how cellular properties give rise to more global brain functions such as synchronous neuronal firing that allows mouse to sense odour; work supported by grants from National Institute of Mental Health, National Institute for Deafness and Other Communications Disorders, Human Frontiers Science Program and Defense Advanced Research Projects Agency. 2005, named one of US top 50 science and technology innovators, Scientific American magazine.
