Dr Sheridan graduated from the University of Chicago, where a teaching assistant first introduced her to the study of frogs in Southeast Asia. She then went on to study the links between health and reproductive success in tropical birds for her MS at the University of Miami. Thereafter, she completed her PhD at the University of California, San Diego, studying reproductive variation in Southeast Asian amphibians. Dr Sheridan taught biology at the University of California Santa Barbara, and a conservation field course in Namibia, Africa, prior to conducting post-doctoral research at the National University of Singapore, exploring long-term changes in amphibian communities and body size responses to climate change. Recently, Dr Sheridan trained in molecular phylogenetics and evolution with Dr Leslie Rissler at the University of Alabama and Dr Bryan Stuart at the North Carolina Museum of Natural Sciences.
Dr Sheridan’s research focuses on understanding and quantifying threats to biodiversity in order to better focus conservation efforts and mitigate change. To those ends, she is currently examining 1) the effects of habitat alteration on amphibian communities, 2) the effect of climate change on organism size, and 3) integrative responses to land use and climate change.
Fragmentation causes both biotic and abiotic changes in local environments, and she is interested in teasing apart top-down and bottom-up factors influencing responses to human-induced disturbances, and identifying which abiotic factors best predict biodiversity. Additionally, changes in body size due to climate warming can alter predictions of population sizes and dispersal abilities, so understanding physiological responses to climate change can improve predictions of species responses to habitat fragmentation. Dr Sheridan aims to develop integrative models to incorporate both physiological and ecological responses to climate and land use changes.
Understanding how species are separated in ecological space and how species are affected by changes in their environment allow for better predictions of biodiversity losses, and potential mitigation techniques.
