Petros A. Ioannou received the M.S. and Ph.D. degrees from the University of Illinois, Urbana, Illinois, in 1980 and 1982, respectively. In 1982, Dr. Ioannou joined the Department of Electrical Engineering-Systems, University of Southern California, Los Angeles, California. He is currently a Professor in the same Department and holds the A.V. ‘Bal’ Balakrishnan Endowed Chair. He is the Director of the Center of Advanced Transportation Technologies and Associate Director for Research of METRANS, a University Transportation Center. He also holds a courtesy appointment with the Department of Aerospace and Mechanical Engineering and the Department of Industrial Engineering. His research interests are in the areas of adaptive control and applications, intelligent transportation systems and marine transportation. Dr. Ioannou was the recipient of the 1985 Presidential Young Investigator Award for his research in Adaptive Control; the 2009 IEEE ITSS Outstanding ITS Application Award; the 2009 IET Heaviside Medal for Achievement in Control by the Institution of Engineering, Technology (former IEE), the 2012 IEEE ITSS Outstanding ITS Research Award and the 2016 IEEE Transportation Technologies Award and the 2017 Transition to Practicve Award by the IEEE Control System Society Dr. Ioannou is a Fellow of IEEE, Fellow of International Federation of Automatic Control (IFAC), Fellow of the Institution of Engineering and Technology (IET) and  Fellow of AAAS. He is the author/co-author of 8 books and over 300 research papers in the area of controls, vehicle dynamics, neural networks, nonlinear dynamical systems and intelligent transportation systems. 




Stephane Hess is Professor of Choice Modelling in the Institute for Transport Studies and Director of the Choice Modelling Centre at the University of Leeds. He is also Honorary Professor in Choice Modelling in the Institute for Transport and Logistics Studies at the University of Sydney, Honorary Professor of Modelling Behaviour in Africa at the University of Cape Town, and has a director position at RSG, a leading North American consultancy company. 

Hess holds a PhD in transport demand modelling from Imperial College London and a MPhil in Statistical Science from Cambridge University. His area of work is the analysis of human decision making using advanced mathematical models. He has made contributions to the state of the art in the specification, estimation and interpretation of such models, as well as in facilitating the transition of ideas and approaches across disciplines, notably by also working in mathematical psychology and behavioural economics. Although a majority of his applied work has been conducted in the field of transport (including leading the modelling on the most recent UK, German and Singaporean national value of time studies, as well as the reestimation of the Swiss study), he is also very active in health and environmental economics. Together with his research team at the Choice Modelling Centre, he is setting the research agenda in applying choice modelling in new fields, including education, lifestyle choices, social (network) interactions and joint decision making. Advanced choice models require high quality data, and Hess and his team are leading the field in exploring and exploiting novel data sources, with numerous applications using ‘big data’.n

Hess has published over 125 peer reviewed journal papers, and his work is highly cited, with a Scopus H-index of 28 (google scholar H-index of 45). He has been involved as a principal or co-investigator in academic projects with a combined income generation of over £9.5M.

His contributions have been recognised for example by the 2017 ICMC award for the most innovative application of choice modelling, the 2014 Outstanding Young Member of the Transportation Research Board (TRB) award for exceptional achievements in transportation research, policy, or practice, the 2010 Fred Burggraf award handed out by the Transportation Research Board, the 2005 Eric Pas award for the best PhD thesis in the area of travel behaviour modelling, and the 2004 Neil Mansfield award handed out by the Association for European Transport. 

He is also the founding editor in chief of the Journal of Choice Modelling and the founder and steering committee chair of the International Choice Modelling Conference. He serves on the editorial advisory board of two other leading journals; Transportation Research Part B and Transportation, as well as academic committees at leading international conferences. Together with David Palma, he is the author of Apollo, a highly flexible and powerful free tool for estimating and applying choice models.
