My research interest is focused on tropical stream ecology, assessing stream dynamics in forested and urban areas. I use a variety of approaches including broad-scale geographic studies, long-term temporal variability and multiple taxonomic groups to understand how climatic phenomena (e.g., drought, ENSO, hurricanes) impact aquatic ecosystems. My research on freshwater ecosystems integrates the social, political and economic realities faced by the diversity of users of this invaluable resource. To achieve these broad aims, I maintain a variety of national and international partnerships across agencies and institutions including governmental, local, regional and international non-governmental
organizations and universities.
