Research interests

My main research interests are: the ecology and ecophysiology of semiarid plant communities; the ecohydrology of water-limited ecosystems; mycorrhizal ecology; asessing the responses of semiarid plant communities to global change; stable isotope ecology; developing ecologically-based criteria for vegetation restoration in degraded ecosystems.
