I hold a Civil Engineering degree (Master Eng. level, ABET accredited) from the Universitat Politecnica de Valencia (Spain), from where I also obtained a later MSc degree in Hydraulic Engineering and Environment. I obtained my PhD from Universite de Liege (Belgium) and worked at the Hydraulics Laboratory of Aachen University of Applied Sciences (Germany) for four years. I have also performed experiments in other hydraulic laboratories (UPV, The University of Queensland, TU Delft, Utah State University).
My main expertise is related to environmental fluid mechanics of multiphase flows, including air-water, water-sediment, and more recently, plastic-water flows; and hydraulic design of engineering structures. I have participated in many novel experimental modelling works and multiphase instrumentation developments, as well as numerical modelling of turbulent multiphase flows. Currently interested in: turbulent transport of plastic flows in rivers and hydraulic structures in the context of climate variability.
