Our research is mainly ecohydrological, in nature, but also touches on physical hydrology, hydrobiogeochemistry and hydropedology. It encompasses the themes outlined below:
Flow processes, i.e., water and chemical transport above ground, in bulk soil, and at ecohydrological interfaces (e.g., soil-bedrock interfaces, soil matrix-macropore boundaries).
Nutrient dynamics in lotic/lentic systems, i.e., mechanisms underlying phosphorus retention and export; metabolic regime of streams and wetlands.
Isotope biogeochemistry, i.e., reliance on stable isotopes of oxygen and hydrogen to estimate mean residence times (i.e., average times water spends in a given watershed compartment), characterize soil evaporation and plant transpiration, and infer plant water uptake.
“Big data” science and modelling, i.e., synthesis and analysis of ground-based and remotely-sensed data from online repositories; use of traditional, equation-based models; custom design of dynamic simulation models (e.g., cellular automata, agent-based models); assessment of modeling uncertainty.
Landscape connectivity, i.e., focus on the movement of water, chemicals, sediment and biota between catchment locations; process conceptualization, modelling and policy implications.
Ecohydrological dynamics in engineered landscapes, i.e., dynamics prevailing in landscapes where natural processes are significantly altered by roads, surface drains, tile drains, man-made reservoirs and wetland loss.
