“I had less difficulty in the discovery of motion of heavenly bodies in spite of their astonishing distances, than in the investigations of the movement of flowing water before our very eyes”.

Galileo Galilei (1564 - 1642)


We investigate fluxes of mass and energy in surface and groundwaters. Our interdisciplinary research involves hydrology, hydraulics, aquatic ecology, chemistry, and mathematical and computational modeling. Despite our major expertise is in engineering and science, we collaborate with water resources managers and policy makers.

Our research interests are: hydrologic transport, stream ecology, groundwater-surface water interactions, smart tracers, wildfires effects in water quantity and quality and hydrology of paramo systems. We investigate interactions between solute transport, metabolism and nutrient cycling, and their relationship within the food, energy and water nexus. We develop and use methods aimed at advancing ecohydrology, ecohydraulics, and civil, environmental and biosystems engineering.



Our lab couples experimental observations with mathematical, numerical and uncertainty modeling to investigate hydrological and biogeochemical processes in stream- and groundwater ecosystems. Some of the methods we are further developing and using are:

  • Semi-continous sensors to understand biogeochemical (carbon and nutrient) processes at multiple temporal scales.
  • Geophysical and stream ecology methods to improve our understanding of solute transport, metabolism and nutrient dynamics.
  • Hydrologic modeling of rainfall-runoff processes and their effects in the mobilization of carbon and nutrients.
  • Mathematical models to investigate transport and biogeochemical processes under uncertainty analyses.
  • Smart tracers (such as resazurin) to better understand the coupling of solute transport and biological reactivity.
  • Scaling techniques to predict hydrological processes.

"We must remember that intelligence is not enough. Intelligence plus character--that is the goal of true education. The complete education gives one not only power of concentration, but worthy objectives upon which to concentrate. The broad education will, therefore, transmit to one not only the accumulated knowledge of the race but also the accumulated experience of social living."

Martin Luther King, Jr. (1929 - 1968)
