Dr Stelios Rigopoulos holds his first degree from Aristotle University of Thessaloniki, Greece (1997) and his MSc degree from UMIST (1999). He obtained his PhD from UCL (2003) and subsequently conducted postdoctoral research at Imperial College London. In 2005 he joined the University of Manchester, while in 2010 he joined again Imperial College London. His research focuses on advanced theoretical and computational methods, including Computational Fluid Dynamics (CFD), Population Balance and Stochastic Methods for modeling physical and engineering problems, particularly with applications to Reactive Flows and Combustion, Multiphase Flows and Particle Dynamics. He has been awarded a Royal Society University Research Fellowship for conducting research in “Nanoparticle Dynamics in Turbulent Reactive Flows” and he is also the recipient of the 2007 Hinshelwood Prize awarded by the Combustion Institute, British Section, to a young researcher for meritorious contributions to combustion science.
