Scientific Contributions

I have been a reviewer for various journals such as Water Resources Research, Environmental Earth Sciences, Hydrogeology Journal, Vadose Zone Journal, Journal of Hydrology, Engineering Geology, Hydrology and Earth System Sciences and International Journal of Heat and Mass Transfer. As an organizer of conference sessions I try to bring together researchers from different communities to enrich the field of recharge and preferential flow dynamics in fractured-porous media.
