Dr. Dinsmore's research is centered on the intersection of avian ecology and population biology and focuses on applied issues related to specific management questions. His research program is important to local, state, and federal natural resource management agencies because it addresses contemporary ecological problems, provides science-based solutions to these problems, and contributes to other natural resource disciplines through methodological advances. His research program has emphasized three primary areas. The first focuses on measures of avian reproductive success, an area where he has played an active role in developing rigorous methods for estimating nest survival.
