Stephen Eubank is deputy director, Network Dynamics and Simulation Science Laboratory, tenured professor, Department of Population Health Sciences, and adjunct professor, Department of Physics. His past research includes fluid turbulence; nonlinear dynamics and chaos; time series analysis of markets (as a founder of Prediction Company); natural language processing (as Visiting Scientist at ATR in Kyoto, Japan); and simulations of large interaction-based systems. As a staff member at Los Alamos National Laboratory, he played a leading role in the development of the traffic microsimulation component of the Transportation Analysis and Simulation System (TRANSIMS), developed the Epidemiological Simulation System(EpiSims) project, and served as team leader for the Urban Infrastructure Suite (UIS), of which both TRANSIMS and EpiSims are parts. UIS is a collection of interoperable simulations of interacting infrastructures, each of which simulates the behavior of every individual in a large urban region. The goal of UIS is to model the dynamics of systems including both physical and social components. Since arriving at the Biocomplexity Institute of Virginia Tech in January, 2005, he has pursued interests both in developing advanced technology for the study of realistic socio-technical systems and also in understanding how the dynamics of diffusive processes on networks, e.g. disease transmission, are related to the structure of the underlying networks. He is the PI on one of the research groups making up the NIH's MIDAS (Modeling Infectious Disease Agent Study) network.
