Professor in Thermophysical Properties, BSc, ACGI, MSc, DIC, PhD, CEng, CSci, MIChemE Vice-Chairman of the Faculty of Chemical Engineering, Aristotle University of Thessaloniki, GreeceMarc Assael received his PhD from Imperial College in 1980 (Supervisor Professor Sir William A,. Wakeham) on the "Measurement of the Thermal Conductivity of Gases". In 1982 he was elected Lecturer in Heat Transfer in the Faculty of Chemical Engineering at the Aristotle University of Thessaloniki, where he founded the Thermophysical Properties Laboratory. In 1986 he was elected Assistant Professor, in 1991 Associate Professor, and in 2001 Professor of Thermophysical Properties at the same Faculty. During the years 1991-1994 he served as the Vice-Chairman of the Faculty and during 1995-1997 he served as the Chairman of the Faculty of Chemical Engineering. Since 2005, the laboratory was renamed Laboratory of Thermophysical Properties and Environmental Processes, in order to take into account corresponding expansion of activities.In 1998, Marc Assael was TEPCO Chair Visiting Professor in Keio University, Tokyo, Japan, while during the years 2007-2010 he also holds the position of Adjunct Professor in Jiaotong University, Xi’an, China. He has published more than 250 papers in international journals and conference proceedings, 20 chapters in books and 6 books. In 1996, his book Thermophysical Properties of Fluids: An Introduction to their Prediction (coauthored by J.P.M. Martin & Th.F. Tsolakis) is published by Imperial College Press (a Greek edition is published by A. Tziola E.), while in 2009, his latest book, Risk Assessment: A Handbook for the Calculation of Consequences from Fires, Explosions and Toxic Gases Dispersion (coauthored by K. Kakosimos), is published by CRC Press (a Greek edition is also published by A. Tziolas E.). He is acting as a referee for most journals in the area of thermophysical properties, while he is also a member of the Editorial Board of the scientific journals- International Journal of Thermophysics- High Temperatures High Pressures- IChemE Transactions Part D: Education for Chemical Engineers- International Review of Chemical Engineering.Marc Assael is a national delegate in many committees in the European Union, in the European Federation of Chemical Engineering as well as in many international scientific organizations. He is married to Dora Kyriafini and has a son called John-Alexander.
