Short introduction

My main research theme is the exchange of heat, water, and momentum through the soil-plant-atmosphere continuum in natural and agricultural systems.  Through understanding of these exchange processes in agricultural systems I seek to develop insights for practical strategies to improve water use efficiency, which becomes crucial with the declining water resources worldwide.  In natural environments my main interest is in studying dew and water vapor adsorption in arid and semi-arid regions and exploring their role in the local hydrological cycle and ecological functioning. 

 

If you are looking for a fascinating research program (master, PhD, post doctorate) you are encouraged to contact me to explore options for joining my group.
