Image of Current Focus for Quantitative Ecology/Survey Design and Analysis

Most of my research involves analysis of survey data.  Designing surveys and estimating status and trends in bird populations are components of this work, but the primary goal of the research is to better integrate surveys with management activities and scientific studies.
