His research interests include fluid flow within marine sediments and its impact on environment and climate, as well as geohazards including shallow gas, gas hydrates, methane emissions, and submarine slope failures. A great part of his research focus on analysis of the evolution of gas hydrate systems under environmental perturbations with the help of numerical modeling techniques.
