My research focus is on the ecology and conservation of seabirds and related colonial waterbirds. I use a variety of approaches to identify factors that characterize and regulate seabird populations including telemetry, energetics, endocrinology, stable isotope analysis, and direct observation of diet, predation, human disturbance, and other potential limiting factors. For threatened and endangered species, I apply research results on seabird breeding habits, foraging ecology, and migratory movements to recommend appropriate and often novel conservation measures. I also investigate the use of more common species as ocean sentinels, both by using seabird diet and reproductive success to indicate the condition of marine food webs, and by using individual animals as sensor platforms to characterize the physical ocean environment. Across my various research efforts, I am fortunate enough to collaborate with partners from academia, government research and management agencies, non-governmental conservation organizations, private environmental consultants, and the public.
My teaching focus on is on sharing experiential learning opportunities in the coastal and marine environment and encouraging critical thinking about complex resource management issues through small group discussions. I regularly offer courses on the ecology of marine and estuarine birds, the behavior and physiology of both marine birds and mammals, and natural resource management problem-solving. These courses are taught in in-person, online, and hybrid formats. In addition to teaching courses, I mentor a number of graduate and undergraduate students at any given time, working with them on a variety of seabird research projects.
