Ecology: Modeling Animal Behavior

New technological Innovations have allowed researchers to collect a wealth of Information as to the activity (via accelerometers) and location (GPS sensors) of animals. This, combined with advances In Bayesian methods for dependent data Is allowing us to better understand the Individual and collective behavior of animals. Our group and partners have been exploring such data with complex spatial, temporal, and spatio-temporal models. Some recent examples Include:
