Where water,
data & nature
converge.

I investigate how land use, climate, and ecosystems reshape catchment hydrology and nutrient dynamics, combining process-based models, Earth observation, and geospatial analysis.

RESEARCH THEMES

Water, landscapes,
and environmental change.

Combining hydrological modeling, field observations, remote sensing and geospatial approaches to explain how catchments respond to environmental and human pressures.

01 / CATCHMENT PROCESSES

Hydrology &
Climate Change

Flow regimes, extreme rainfall, groundwater–surface water interactions and land-use change.

02 / NUTRIENTS

Water Quality &
Nutrient Dynamics

Nitrogen and phosphorus budgets, event-driven nutrient transport and watershed–coastal connections.

03 / ECOHYDROLOGY

Remote Sensing &
Ecohydrology

Forest growth, evapotranspiration, water–carbon interactions and Earth observation.
