My current research is focused on understanding past and modern plant species distributions and associated climates in the Atacama Desert and Pacific slope of the Andes of northern Chile. Over the last few years, my collaborators and I have been using midden records (bones, plant material, insects and feces accumulated by rodents, encased in a solid crystalline matrix of urine, and preserved for thousands of years in rock shelters and caves) from the Atacama and adjacent semiarid regions to identify fluctuations in the regional hydrological cycle over the last 40,000-50,000 years. The Andes Cordillera of northern Chile (in the central Andes) straddles both the tropical and extratropical rainfall belts. My main research objective is to increase our understanding of how these climate systems have interacted in the past (through investigating the chronology, direction and structure of climate changes) and how they might do so in the future. On the other hand, as our knowledge on the distribution and diversity of past desert plant communities in northern Chile increases, we seek to understand the implications for biogeography and eventually, conservation of modern desert communities, many of which have been highly dynamic through time. Other recent lines of collaborative research involve aspects related to past climate and groundwater formation in northern Chile and the recent history of the unique Tillandsia fog ecosystems found in northern Chile.
