Rainer Helmig

Rainer Helmig is head of the Department of Hydromechanics and Modelling of Hydrosystems in the Faculty of Civil and Environmental Engineering at the University of Stuttgart, Germany His research covers groundwater hydrology, multi-phase flow in porous media, numerical modeling, and the analysis of coupled processes between the unsaturated zone and the atmosphere. Special focus is on coupling hydrosystem compartments and complex flow and transport processes, as well as integrating data and models. Emphasis in on fundamental questions about physical and mathematical modeling of multi-phase processes, developing algorithms accounting for fluid phase changes and structural media heterogeneities, thereby forming a basis for various model concepts (e.g. pre-dimensioning decontamination strategies and analyses of energy storage (gas, heat), including their effects on groundwater). Recent research focuses on understanding and modeling mass- and heat-flux processes across the land/atmosphere interface as controlled by dynamic interactions between the atmospheric boundary layer and the land surface. Contributes to developing new model concepts to enhance understanding of land-atmosphere interactions, evaporation and evapotranspiration processes, climate modelling, and salt precipitation.

Jan Nordbotten

Jan Martin Nordbotten is a professor of mathematics at the University of Bergen, working on problems inspired from geosciences, biology, and biomedicine. He completed his PhD in Bergen in 2004 at the age of 22 as the youngest ever in Norway, and became a full professor when he was 28. He has received national and international recognition for his research, including the inaugural SIAM Geosciences Junior Scientist award in 2009. Nordbotten has published more than 120 papers in collaborations with over 100 researchers, and co-authored together with Michael A. Celia the first text-book on modelling and simulation of subsurface CO2 storage.

Adriana Paluszny

Dr Adriana Paluszny is a Senior Lecturer in the Department of Earth Science & Engineering, Imperial College London. She has a PhD in Computational Geomechanics from Imperial College London and has served as a Post-Doctoral Research Associate in the Rio Tinto Centre for Advanced Mineral Recovery at ICL, as a Research Fellow funded by the UK’s Engineering and Physical Sciences Research Council and the UK’s Natural Environment Research Council. She currently holds a Royal Society University Research Fellowship that allows her to conduct research in the area of fracture mechanics and coupled deformation. Adriana is the recipient of the “Chin-Fu Tsang Coupled Processes Award 2019”, and a member of the “Commission on Coupled Thermal-Hydro-Mechanical-Chemical Processes in Fractured Rock” of the International Society for Rock Mechanics and Rock Engineering. Her research is primarily focused on the robust numerical modelling of multiple fracture growth in three dimensions, with applications to geomechanical modelling of fluid injection, hydraulic fracturing, rock drilling, effective permeability of fractured rocks, and emerging methods in computational fracture mechanics. She is interested in understanding how growth is affected by heterogeneities at multiple scales and how the interplay between fluid flow and mechanics affects these interactions. Adriana also runs the outreach project “Watson Forum”, micro-interviewing women in computational modelling and other STEM areas (

Monica Riva

Monica Riva is Professor at the Politecnico di Milano, PoliMI (Italy), Department of Civil and Environmental Engineering. She is also Adjunct Professor at the Department of Hydrology and Water Resources of the University of Arizona (USA). Monica received her Ph.D. in Environmental and Infrastructure Engineering from the PoliMI in 2000. She has been visiting Professor in several Universities and Research Centers, including the University of Arizona, the University of Strasbourg and the CNRS (France). Her research activity has been focused mainly on subsurface flow and transport dynamics, stochastic groundwater hydrology, probabilistic well protection zones, scaling in hydrology and model parameter estimation, uncertainty quantification, multiphase flows and groundwater management. One of her main contributions is the development of exact and approximated formalisms for the characterization of key processes governing spreading of conservative and reactive solutes in hydro-geo-chemically heterogeneous geomaterials by means of a rigorous probabilistic framework. She developed and applied innovative stochastic and upscaling techniques to study flow features of immiscible and miscible fluids. She has developed a theory (based on the concept sub-Gaussian mixtures) able to capture the (typically non-Gaussian) scaling behavior exhibited by many hydrological-hydrogeological-environmental variables. She has introduced novel metrics to perform global sensitivity analysis and ensuing uncertainty quantification across multiple interpretive models with uncertain parameters.
Monica serves as Elected Member of the Council of InterPore (International Society for Porous Media), Deputy Coordinator of the Doctoral Program in Environmental and Infrastructure Engineering at PoliMI and Rector Delegate for International Networks at PoliMI. She has recently coordinated the European Water JPI project “WatEr NEEDs, Availability, Quality and Sustainability”.
