Research Interests


Describing the reciprocal influences between the biosphere and the atmosphere are becoming a scientific imperative as human-induced changes in land surface characteristics are impacting the composition of the atmosphere, which in turn is threatening to excite changes in weather and climate systems. The concentration of efforts to quantify these influences and to develop a predictive framework for them has given rise to a new research field labelled "land-atmosphere exchange".  This field is now populated by a community of scientists and engineers originally trained in a cross-section of disciplines.  My particular research interests in this domain cover mass, momentum, and energy transfer within the soil-plant-atmosphere system.  This domain intersects micro-meteorology, surface hydrology, ecology and carbon/water cycling, and fluid dynamics that spans low and high Reynolds numbers.
