Control theory, economics of climate change, nonlinear systems, robust control systems, signals and systems, social systems, stability theory.
Professor Kellett’s research interests are broadly in areas referred to as mathematical systems theory, autonomous systems, control engineering, or (new) cybernetics, with a focus on analysis and design of nonlinear systems. He is particularly interested in stability and performance of nonlinear systems with applications in power networks, telecommunications, signal processing, social systems, and the economics of climate change. Together with Dr. Philipp Braun, Professor Kellett has co-authored the textbook Introduction to Nonlinear Control: Stability, Control Design, and Estimation (Princeton University Press, 2023).
Professor Kellett has been the Director of the ANU School of Engineering since 2020. Prior to this, he held several roles at the University of Newcastle (Australia), including Associate Dean Research for the Faculty of Engineering & Built Environment. Professor Kellett has held several research fellowships, including an Australian Research Council Future Fellowship (2012-2015), a Research Fellowship from the Alexander von Humboldt Foundation (Germany, 2012-2013), and was named an International Senior Fellow by the University of Bayreuth (Germany) for 2016-2018. Before joining the University of Newcastle in 2006, he held positions at the Hamilton Institute, National University of Ireland Maynooth, the University of Melbourne (Australia), and Ecole des Mines de Paris (France).
Professor Kellett received his BSc degrees in Electrical Engineering and Mathematics at the University of California Riverside in 1997, and his MSc and PhD, both in Electrical and Computer Engineering, from the University of California Santa Barbara in 2000 and 2002, respectively.
Activities & Awards
Professor Kellett currently serves as a Senior Editor for the IEEE Transactions on Automatic Control and an Associate Editor for Mathematics of Control, Signals and Systems. He has previously been an Associate Editor for IEEE Control Systems Letters, the European Journal on Control (2013-2019), and was a member of the IEEE Control Systems Society Conference Editorial Board from 2007-2017. He has served on the International Program Committees for several International Federation on Automatic Control (IFAC) conferences and was the General Chair for the 12th IFAC Symposium on Nonlinear Control (IFAC NOLCOS) held in Canberra in January 2023.
Professor Kellett has been awarded the 2012 IET Control Theory and its Applications Premium Award, the inaugural IFAC Foundation Award (now the ) in 2017, and the 2011 University of Newcastle Vice-Chancellor’s Award for Teaching Excellence in the Faculty of Engineering and the Built Environment.
