I'm an aquatic ecologist interested in the influence of human activities on water quality and stream functional processes- including nutrient cycling and aquatic primary production and respiration.


  • PhD, 2010, Fundamental and Applied Ecology, Universitat de Barcelona, Spain.
  • MSci, 2002, Environmental Biology, Universitat de Girona, Spain.
  • BS, 1998, Biology, Universitat de Girona, Spain.

Areas of interest:

  • Water quality
  • Effects of hydrology and morphology on stream function
  • Forest-stream interactions
  • Functional processes in stream ecosystems - nutrient cycling, respiration, and primary production
  • Ecology of the hyporheic zone

Graduate Students:

Currently working in the following projects:

Spatial scales, aquatic consumers, and metabolic rates

Can we use small scale experiments to explain structure and function of regional ecological systems? Does the presence of fish and amphibians modify stream respiration and primary production rates? or nutrient uptake?

Use of bioengineering techniques to improve water quality - INTERFACES

Interfaces is a Marie Curie Initial Training Network, funded by the European Union, with the objective to train a new generation of transdisciplinary aquatic scientists. Its research focuses on ecohydrological interfaces as critical hotspots for transformations of ecosystem exchange fluxes.

Effects of forest harvest on stream water quality and function

How does forest harvesting affect stream nutrient concentrations? And aquatic primary production? Do we see a change in the aquatic food web? Does the presence of buffers make a difference?
In this multiagency, multiyear project we study the effects of contemporary forest practices on aquatic ecosystems.
