Nancy Nersessian is Regents' Professor and Professor of Cognitive science at Georgia Institute of Technology. She holds appointments in the School of Public Policy and the College of Computing, and Adjunct Professor in the College of Architecture.  She is a member of the Program in Philosophy, Science, and Technology and of the Program in Women, Science, and Technology. Her research focuses on the nature and processes of conceptual innovation and change in science; specifically, investigating the role of analogical and visual modeling and thought experimenting (simulative modeling) in conceptual change, both in science and in science education. She is author of numerous publications on these topics, including her recent book, Creating Scientific Concepts, published by MIT Press. Professor Nersessian's current work investigates the cognitive strategies used by biomedical engineering scientists, especially physical and computational simulation models, and learning practices in their research laboratories. She has been working with her co-PI, Wendy Newstetter, to design problem-driven learning environments in classrooms and in instructional labs. Professor Nersessian was elected a Foreign Member of the Royal Netherlands Academy of Arts and Sciences, a Fellow of the American Association for the Advancement of Science, Fellow of the Cognitive Science Society, and served as Chair of the Cognitive Science Society. She has been a Fulbright Research Scholar to the University of Leiden, the Netherlands, a Fellow of the Netherlands Institute for Advanced Study, a Senior Fellow of the Pittsburgh Center for the Philosophy of Science and a Fellow of the Radcliffe Institute for Advanced Study. She has taught at several institutions, including the Technical University of Twente, the Netherlands and Princeton University. She has held grants from NEH and NSF, has been a member of the national review panel for the Science, Technology, and Society Program at NSF, and an elected member of the Governing Board of the Philosophy of Science Association. In her spare time she performs in opera and recitals.
