I obtained my PhD degree at UNSW in Petroleum Engineering in 2002 and hold a Dipl. Phys. from RWTH Aachen. From 2001-2008 I was a research fellow at the Australian National University in the Department of Applied Mathematics. I am a pioneer in the area of Digital Rock Physics (20 years) and specialize in the area of computational pore-scale physics based on tomographic images including the integration of digital and conventional core analysis. My primary interest lies in the combination of 3D tomographic imaging technology and NMR spectral techniques for (petro-)physical applications with a particular focus on heterogeneity. This work was substantially supported by the Australian Research Council (ARC) through three successive ARC fellowships.
I was an integral part and founding member of a team commercialising digital core analysis through the ANU/UNSW spin-off Digital Core Pty Ltd, formed in 2009. This company merged to Lithicon and was sold in 2014 to FEI for $76m. It is now part of ThermoFisher. My main contribution is in the area of computational physics through the MPI-parallel software package morphy, which consists of a set of solvers operating on segmented tomographic images, including sophisticated NMR response modeling, electrical property calculations, permeability, elastic moduli, and morphological properties and geostatistics.
Professional I am active member of multiple societies, including Interpore where I was chair of council (2016-2019) and remain life-time member, the Society of Core Analysts (SCA), where I am Australasia Regional Director (2016-) and life-time member, the Society of Exploration Geophysicists (SEG), where I am Associate Editor of Geophysics since 2017. Furthermore the Groupement Ampere (MRPM representative (2012-2018)), Society of Petrophysicists & Well Log Analysts (SPWLA), where I am currently member of the Awards Committee, and the Society of Petroleum Engineers (SPE).

My Research Activities
High-resolution micro-CT imaging enables the calculation of (petro-)physical properties of materials utilizing known micro-structure. This is the basis of digital core analysis. Example: small section of Leopard sandstone at 2.47um resolution.
For complex physical responses, a match to experiment may pose an inverse problem. Achieving such a match offers both classical interpretation approaches, but also new methods based on the extracted intrinsic parameters constrained by imaging. Example: NMR relaxation response.
Integrating digital core analysis, which operates at the pore scale, into industry workflows at larger scales requires the mapping of pore-scale features to continuum measures – here shown for the Minkowski measures.
