Professor Stephan K. Matthäi earned a Diplom (MSc) degree in structural geology from the Eberhard Karls University of Tübingen, Germany, and a PhD focusing on the characterisation and numerical simulation of hydrothermal gold deposits from the Research School of Earth Sciences at the Australian National University, Canberra. He conducted postdoctoral research on hydrocarbon systems in the Gulf of Mexico basin at Cornell University, and fluid flow in fractured rock masses at Stanford University. At the Swiss ETH Zürich, he implemented subsurface fluid convection and heat transfer models. In 2001, he became a Senior Lecturer of Computational Hydrodynamics at Imperial College London, UK, focusing on multiphase flow in fractured hydrocarbon reservoirs. Prior to joining the University of Melbourne, he was Chair and Head of the Petroleum Reservoir Engineering Institute at the Montanuniversitaet Leoben, Austria. His publications range from meteorite impact cratering to the formation of hydrothermal gold deposits, and the development of new computational algorithms. Perhaps he is best known for his contributions to the understanding of multiphase flow in fractured porous media and multidisciplinary field- and numerical simulation studies. He also is the originator of the Complex System's Modeling Platform (CSMP++), a hybrid finite element - finite volume tool for the solution of multi-physics problems in geometrically complex models, enjoying a growing international user community, both in academia and the O&G industry. In this role, he has consulted extensively to company research labs and operators. Collaborative research efforts involve scientists at the ETHZ (Switzerland), Heriot Watt University (Scotland), Imperial College London (UK), and ENSG Nancy (France). They underpin multidisciplinary field and numerical simulation studies and are financed by government grants, industry consortia and individual stakeholders. At Imperial College London and as the head of the Reservoir Engineering Institute in Leoben, Matthäi has delivered numerous keynote lectures on international conferences. He has co-organised and chaired SPE's 2006 and 2008' Fori on Naturally Fractured Reservoirs and served on the organising committees of many other SPE and EAGE events. Professor Matthai also has a strong interest and track record in teaching, course- and curriculum design. In addition to teaching conventional petroleum engineering and earth science subjects, he has lead field trips, supervised field camps and mapping courses as well as classes and workshops in C++ programming and numerical simulation. He also has delivered professional short courses for the SPE and HOT engineering.
