I am fascinated by the interface of the above- and below ground systems. The soil environment is shaped from above and from within. Understanding the interactions of soil biota with each other and with changing resources or environment are themes that come up repeatedly in my research.
I am currently investigating methods to restore biocrusts in disturbed ecosystems. We are doing this by:
1. Learning the best ways to optimize growth, establishment and ecosystem functions in the field by modifying:1) inoculum amounts, 2) modifying habitats, and 3) enhancing soil stability.
2. Bringing biocrust organisms to the lab and greenhouse to determine how best to cultivate them as an inoculum source, and then, how best to reintroduce them to the environment.
