Personal profile

Research interests

I am the Director or Research for the School of Energy, Geoscience, Infrastructure and Society (EGIS) and the Energi Simulation Chair in Carbonate Reservoir Simulation. In the latter role, I head the Carbonate Reservoir Group at the Institute of Geoenergy Engineering (IGE). I served as the Director for IGE from 2017 to 2020.

Together with the Carbonate Reservoir Group and colleagues at the International Centre for Carbonates, I conduct fundamental and applied research on improving the sustainable management of geo-resources in carbonate and fractured reservoirs, from hydrocarbon production to CO2 storage and geothermal energy.

Our research activities include, but are not limited to, pore-scale studies of multi-phase and multi-component transport, micro-X-Ray CT visualisation of flow processes, upscaling flow and transport in fractured reservoirs, near-wellbore flow processes, feedback between carbonate reservoir architectures and fluid flow, numerical method development, and history matching.


I joined the Institute of Petroleum Engineering (now Institute of GeoEnergy Engineering) in 2006 as a lecturer. I was promoted to senior lecturer in 2009 and as full professor in 2010. In 2017 I became the Director of IPE. Before joining IPE, I was a postdoctoral researcher at ETH Zurich from 2004 to 2006.

I obtained my PhD degree in computational geosciences from the ETH Zurich in 2004 and hold an MSc degree in geosciences from Oregon State University. I was a visiting researcher at Aramco Services Company in Houston in 2015, at the Department of Earth Science and Engineering at Imperial College in 2006, and was a visiting fellow at the Department of Mathematics at Australia National University in 2001.

I am serving on different technical and strategic committees of the European Association of Geoscientists and Engineers (EAGE). I am also a member of the Society of Petroleum Engineers (SPE), for which I have chaired panel discussions (e.g. 2013 RSCS or 2014 ADIPEC) and serve on technical conference committees (e.g. 2016 ATCE, 2011, 2013, and 2019 RSCS, or 2017 and 2019). I co-convened the 2012 joint AAPG-SPE-SEG Hedberg Research Conference on Fundamental Controls of Flow in Carbonates in France. I served on the editorial board for Transport in Porous Media and am currently serving on the editorial board for Petroleum Geoscience.

I received the Interpore Rosette for outstanding contributions to the society in 2015. In 2017 I received the EAGE Alfred Wegener Award for my group's groundbreaking research in carbonate reservoir modelling and simulation. I was elected as a Fellow of the Energy Institute in 2019, and became a Fellow of the Royal Society of Edinburgh in 2020.

I have provided consultancy to the energy industry on some major technical issues, for example on the links between gas production and subsidence in the Wadden region, Netherlands. I also teach regularly CPD courses to the energy industry, for example at ENI Corporate University on applied reservoir simulation.
