I'm interested in the interactions between soil, water and vegetation in drylands, in both natural and agricultural ecosystems. Our goal is to understand how the basic processes and feedbacks influence the dynamics of the system, and how this knowledge can be used to control those systems.

Projects: Soil-plant-atmosphere continuum

Biosphere-atmosphere gas exchange & Atmospheric Chemistry

• How climate change and air-pollution affect and being affected by changing the natural balance between the biosphere and the atmosphere?

• How can we save water by improving evapotranspiration prediction, using atmospheric and soil modeling, combined with remote sensing?

71618: Introduction to Soil Chemistry

Course Level: undergraduate
Concept of the course: Demonstration of the interrelations between chemistry of soil components and soil processes, and between solid and liquid phases in soils. The importance of interfacial reactions is emphasized.
