Profile

Biography

Dr Guven Demirel is a Lecturer of Logistics and Supply Chain Management at Essex Business School - Management Science and Entrepreneurship Group. He has an academic background in industrial engineering and physics and works on interdisciplinary problems in the field of complex systems. He has expertise in developing analytical and simulation methods for investigating dynamical processes on complex socio-economic networks. His research brings together methods from various mathematical disciplines including operations research, applied mathematics, and physics for the study of problems such as information spreading on social networks, resilience and robustness of supply networks, and improvement of supplier capability. He is the author of five journal articles in prestigious journals including Science, Physica D, New Journal of Physics, European Physical Journal B, and Advances in Complex Systems. Prior to joining Essex Business School, Guven worked as researcher at Nottingham University Business School and Max-Planck-Institute for the Physics of Complex Systems. Guven holds a PhD in Physics from Dresden University of Technology, Dresden, Germany.
