in 1976.
Since 1977, Sontag has been with the Department of Mathematics at Rutgers University
, The State University of New Jersey, where he is currently Professor of Mathematics as well as a Member of the Graduate Faculties of the Department of Computer Science and of the Department of Electrical and Computer Engineering. He is also the director of SYCON, the Rutgers Center for Systems and Control, and is a co-founder and Member of the Steering Committee of the BioMaPS Institute for Quantitative Biology.
He is in the Editorial Board of IEE Proceedings Systems Biology, SIAM Review Synthetic and Systems Biology International Journal of Biological Sciences, Journal of Computer and Systems Sciences, and Neural Computing Surveys (Board of Advisors), and a former Board member of IEEE Transactions in Automatic Control, Systems and Control Letters, Dynamics and Control, Neurocomputing, Neural Networks, Control-Theory and Advanced Technology, and Control, Optimization and the Calculus of Variations. In addition, he is a co-founder and co-managing editor of Mathematics of Control, Signals, and Systems.
Sontag is an Institute of Electrical and Electronics Engineers
