Research

My research interests focus on the ecology and conservation of wetland- and prairie-dependent wildlife, particularly waterfowl. Recent research has focused on better methods of estimating population size of wetland and grassland wildlife, estimation of population vital rates (e.g. nest success, brood survival), and development of population models to guide management activities and predict future population trajectories.
