Charles Morrison Professor of Physics and Astronomy

Ph.D. in Applied Mathematics, State University of Campinas, Brazil, 2002; B.S. in Physics, State University of Campinas, Brazil, 1996

Research Interests

The Motter Group studies studies how information, influences, and perturbations propagate through complex networks and how they shape the large-scale behavior of systems as diverse as biochemical, physical, and ecological networks. This research touches upon issues underlying the root causes of spontaneous synchronization, behavioral cascades, and other collective phenomena observed in many natural and man-made systems. In particular, the group has helped develop the concept of synthetic rescue in network biology, which is a collective gene interaction effect that can compensate for genetic and epigenetic failures in living cells. Current research includes optimization and control of network dynamics for the recovery of lost cellular function, the development of smart grids, the design of new materials, and the stabilization of complex systems.

This research is inherently interdisciplinary and benefits from Prof. Motter's affiliations with other programs, such as the Department of Engineering Sciences and Applied Mathematics (ESAM), Department of Linguistics, Molecular Biophysics Program, Northwestern University Physical Sciences-Oncology Center (NU PSOC), Initiative on Sustainability and Energy at Northwestern (ISEN),  Institute for Sustainable Practices (NiSP), Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA), and Northwestern Institute on Complex Systems (NICO).
