I work passionately on the sustainable use and management of the soil system. I am trying to unravel the causes of soil change in space and time and I am intrigued by questions such as: what makes soil tick, and how, where and when does it grow? I seek to develop answers to such questions through the combination of observation and quantitative theory. The understanding that provides answers to such questions helps us to create sustainable ecosystems and provide food, water and energy for humanity more securely.
