Biography
Sontag received his Licenciado degree from the Mathematics Department at the University of Buenos Aires in 1972, and his Ph.D. in Mathematics under Rudolf Kalman at the Center for Mathematical Systems Theory at the University of Florida 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.
He has been Program Director and Vice-Chair of the Activity Group in Control and Systems Theory of Society for Industrial and Applied Mathematics (SIAM). He has been a member of several committees at SIAM and the American Mathematical Society, and is a former Chair of the Committee on Human Rights of Mathematicians of the latter.
Work
His work in control theory led to the introduction of the concept of input to state stability (ISS), a stability theory notion for nonlinear systems, and control-Lyapunov functions. Many of the subsequent results were proved in collaboration with his student Yuan Wang and with David Angeli. In systems biology, Sontag introduced together with David Angeli the concept of input/output monotone system. In theory of computation, he proved the first results on computational complexity in nonlinear controllability, and introduced together with his student Hava Siegelmann a new approach to analog computation and super-Turing computing.
Awards and honors
Sontag is an Institute of Electrical and Electronics Engineers (IEEE) Fellow. He was awarded the Reid Prize in Mathematics in 2001, the 2002 Hendrik W. Bode Lecture Prize from the IEEE, the 2002 Board of Trustees Award for Excellence in Research from Rutgers University, the 2005 Teacher/Scholar Award from Rutgers University, and the 2011 IEEE Control Systems Award. In 2012 he became a fellow of the American Mathematical Society.
Publications
He has authored three books and is an ISI Highly Cited researcher:
