My research is centered on the intersection of avian ecology and population biology and focuses on applied issues related to specific management questions. I have a particular fondness for waterbirds, especially shorebirds, gulls, and terns. My research program has emphasized three primary areas including (1) measures of avian reproductive success, (2) modeling avian demography, and (3) influence of habitat on populations. Research projects include Black Skimmers and Least Terns in Mississippi, grassland birds in the Mississippi Delta, secretive marsh-birds in Iowa, population biology of the Devils Hole Pupfish, breeding biology of the Puerto Rican Bullfinch, breeding biology of the Long-billed Curlew, and Mountain Plover population biology in Montana.
