Our research focus is on digital rock methods, reservoir simulation, multiphase flow through porous media with applications in minerlas, groundwater, oil and gas industry. Our expertise incorporates both numerical and experimental methods including: finite elements, X-ray microcomputed tomography, pore network modelling, microfluidics, special core analysis, and discrete fracture network modelling. Most recently, we have developed advanced computer vision and machine learning methods for the study of rocks and predictive modelling. Here, you will find some of recent publications.
