We are a dynamic research team affiliated with the Group of Geoenvironmental Processes and Global Change at the National Museum of Natural Sciences-CSIC, in Madrid (Spain). Our expertise lies in the study of hydroclimatic extremes (floods and droughts) and their connection to Climate Change. With extensive experience in palaeoflood hydrology, historical hydrology, and natural hazards in mountain environments, we employ a multidisciplinary approach. Our methods encompass geomorphology, dendrochronology, the study of lake sediments, remote sensing, statistics, and physical-based hydrological and hydraulic modeling. From local to global scales, we investigate the magnitude and frequency of floods and droughts, exploring both singular events and integrated multi-processes with cascading effects in basins. Additionally, we provide frequency-magnitude reconstructions of hydrogeomorphic processes in mountain regions, including debris flows, landslides, and snow avalanches, while also investigating how forest ecosystems respond to such disturbances. Furthermore, we contribute to the field of paleoclimatology by identifying environmental changes that drive past climate variability.
