I am interested in how various process affect the patterns of species distribution we observe in nature. These processes include climate, human impacts, demography, dispersal and, increasingly, species interactions. I obtained my bachelors in biology at Whittier College, USA, in 2003, and during the following 5 years I worked with botanical inventories, conservation GIS and teaching biology in South America. In 2010 I obtained my Masters degree at the University of Uppsala, Sweden. For my thesis I collaborated with Miguel Araújo, and we investigated the effects of threshold-setting methods on range shift projections for Bioclimatic Envelope Models. Currently I am working with the Rui Nabeiro Biodiversity chair, integrating spatially-explicit demographic models with Bioclimatic Envelope Models.
