Specialty: South America and Southern Hemisphere paleoclimates and inter-hemispheric paleoclimate correlations.

Research Interests: Late Quaternary palynology primarily in southern South America and other land areas in the southern hemisphere with focus on reconstruction of past climate, dynamics and forcing of climate change, especially during times of transition, such as the late glacial. Development of national and international research initiative PEP 1 (Paleoclimates Pole-Equator-Pole in the Americas) in context of PAGES-IGCP.

Present Research: High resolution, multi-proxy paleoclimate analysis, using pollen (vegetation history), charcoal (fire history), and stable isotopes (temperature history) from late-Quaternary lake and bog sediments in southern South America, in collaboration with J. W. C. White and E. Pendall (both INSTAAR) and INSTAAR graduate students. International cooperative research: Patagonian Lake Drilling Project (PATO), focusing on recovery and multi-proxy analysis of sediment cores from large, extra-Andean lakes. Editor of volume "Interhemispheric Climate Linkages", published in 2000 by Academic Press, representing the outcome of the "Pole-Equator-Pole Paleoclimates of the Americas" (PEP 1) IGBP-PAGES research initiative, that I previously chaired. Co-editor with H.F. Diaz of the volume "El Niño and the Southern Oscillation: Multiscale Variability and Global and Regional Impacts", published in 2001 by Cambridge University Press.
