Post-doctoral Research Associate

Primary Responsibilities: 
Beth is a post-doc working with Dr. Allan O'Connell on modeling of sea bird distributions in the western North Atlantic.  Her other research interests include estimating abundance with spatially explicit hierarchical models, including capture-recapture data from trapping arrays, combining misaligned data, and estimating spatially explicit trends of abundance.
