Ecohydrology | Climate Change | Sustainable Development



Vegetation regulates terrestrial water, carbon, and energy cycles at local to global scales as it responds and adapts to changing environmental conditions, driven by natural dynamics and human intervention.

Characterizing interactions between hydrology, climate, and primary production, which are regulated by vegetation within a day as well as over decades, is critical to manage water, food, and energy for ever growing demands in a changing environment.


Current interests:


Diagnose vegetation water-carbon tradeoffs and response to stress, encoded in observations from plant to satellite scales.

Quantify key ecohydrological parameters and eco-evolutionary optimality principles that enhance our understanding of complex environmental systems.

Provide acurate and tractable criteria for sustainable climate risk reduction by combining data-driven and process-based methods.


Questions adressed in on-going projects include:

When do plants reduce growth to conserve water and how do plant water use strategies interact with hydrology and climate variability?

How much ecohydrological information can be extracted from remotely-sensed observations and how useful are these data for managing natural resources?

What level of model complexity provides adequate predictive and causal information about ecosystem-scale water and carbon fluxes?
