His work addresses the effects of vegetation change (including land use change) on ecohydrological processes in tropical, as well as temperate, ecosystems. His work includes multiple spatial and temporal scales, from plot to subcontinental scales and their link to ecosystem regulation services. His current work addresses the effects of land use change in tropical Mountain ecosystems in the central Andes of Colombia and how these chances can affect water and soil dynamics in these highly strategic systems. He is also working on understanding the effects of large scale ecosystem effects on climate via atmospheric transport of moisture and ecoclimatic teleconnections, with a focus on the Amazon forest as a key regulator of South American precipitation dynamics.
