Personal profile

Research interests

I am the Director for the Institute of Petroleum Engineering (IPE) and the Energi Simulation (formerly known as Foundation CMG) Chair in Carbonate Reservoir Simulation. In the latter role, I head the Carbonate Reservoir Group at IPE and serve as the Co-Director of the International Centre for Carbonates (ICCR).

Together with the Carbonate Reservoir Group and colleagues at ICCR, I conduct fundamental and applied research that aims to improve our ability to characterise, model, and simulate hydrocarbon recovery from carbonate and fractured reservoirs. We also started to map our learnings to wider geoenergy challenges such as geothermal energy or CO2 storage.

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, enhanced oil recovery (particularly water-alternating gas injection), heat transport, and history matching.


I joined the Institute of Petroleum Engineering (IPE) 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 a member of the technical committe for the Oil and Gas Geoscience Division of the European Association of Geoscientists and Engineers (EAGE) as well as a founding member of EAGE's Reserves Committee. I am 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 and 2013 RSCS, 2017 RSC). In the past, I was an elected council member and chair of the awards committee for the Interpore Society, for which I received the Interpore Rosette for outstanding contributions to the society. I am also a regular member of the  American Geophysical Union (AGU), Geological Society of America (GSA) and the American Association of Petroleum Geologists (AAPG). I co-convened the 2012 joint AAPG-SPE-SEG Hedberg Research Conference on Fundamental Controls of Flow in Carbonates in France.

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.
