Áreas de investigación:
Soy hidrólogo y mi investigación está enfocada en la medición y simulación de procesos de la generación de escorrentía y el almacenamiento de agua y sustancias biogeoquÍmicas. Mi motivación principal es la comprensión y cuantificación de sistemas dinámicos para llegar a facilitar una toma de decisiones informada por métodos científicos rigurosos. Para mayor información consulte mi repositorio personal.
My research broadly focuses on catchment hydrology and the measurement and modelling of streamflow generation and biogeochemical processes. The basic aim is to better understand catchment functioning and the great variability of hydrological behaviours across different temporal and spatial scales. Insights from my research can be applied to assess the impacts of stream regulation and environmental change on the quality and quantity of surface waters with the objective to inform a sustainable management of water resources. More specifically, I am interested in tracer techniques to better understand dynamic catchment behaviour, the development and application of parsimonious rainfall-runoff models coupled to solute and biogeochemical processes, impacts of environmental change on the hydrology in tropical regions and statistical time series modelling to explore temporal patterns in environmental data.
