For my graduate research, I hope to better understand the influences of ecology and physiology on animal behavior. Specifically, the demographic consequences of environmental change and anthropogenic resource extraction are pressing global issues. Climate change is already impacting polar marine environments, the species that inhabit these areas, and the human communities that rely on local natural resources. Remarkably, the sensitivity of many species to predicted climate scenarios have yet to be quantified. Some questions of critical importance include: (1) How will species respond to global change, in terms of fine-scale behavior, large-scale distribution, and long-term demographic patterns?; (2) What mechanisms are driving these shifts; and (3) How can we use our knowledge of these mechanisms to plan effective conservation and management strategies and thus preserve ecosystem integrity? I plan to address these questions by combining prediction modeling with empirical methods such as remote weather sensing, anesthesia procedures, and advanced biotelemetry.

Broadly, I am interested in the ecology and conservation of Arctic-breeding shorebirds. My research focuses on whether and how winter-time stress may carry over to affect reproductive success in individuals. I am also looking at connections between breeding and wintering populations to see whether individuals from one population experience similar levels of stress versus those from other populations.

Broadly, I am interested in techniques used to assess wildlife and ecosystem health status. Specifically, I am measuring plasma metabolites in Steller sea lion pups on Russian and Alaskan rookeries (1990-2015); the profile generated allows us to assess nutritional stress, which is often proposed as an explanation for population declines and/or non-recovery. These results are paired with morphometric body condition indices and evaluated with respect to the population trajectories in each distinct population segment.

Feeding ecology of Lesser scaup ducklings on the Yukon Flats NWR and their vulnerability to trophic mismatch. Generally, I am interested in wetland ecology and conservation; avian ecology, conservation and management; stable isotope ecology; avian energetics; aquatic entomology; land management; climate change.

Hyporheic habitats may play a major role in shaping stream food webs and are likely very susceptible to warming temperatures. Climate change and resource development could alter the trophic linkages between surface and subsurface habitats upon which stream food webs depend. Understanding these linkages better, in the face of increasing resource development and climate change, will help inform aquatic resource management. The objectives of my research are to determine 1) how water temperature influences invertebrate community assemblage, density, and diversity at the stream surface-subsurface interface, and 2) how hyporheic communities and processes influence stream food webs.

Generally, I am interested in the spatial ecology and movement of seabirds once they depart their breeding colonies, and the ways in which oceanographic variability affects seabird productivity. Specifically, my masters work will address questions related to age-specific reproductive strategies of Cassin's auklets, along with their winter dispersal patterns from Southeast Farallon Island, California.

My focus is systematic entomology, specializing on beetles (order Coleoptera). My thesis project is a taxonomic revision of the rove beetle genus Phlaeopterus (Coleoptera: Staphylinidae: Omaliinae). I am a proponent of integrative taxonomy, and I am using both morphological and molecular data in my research.

Nutritional therapy(NT) consisted of essential amino acids is proven to preserve net muscle masses in athlete/elderly. My research is to use similar nutritional formula to reverse reductions in protein synthesis and liver function of alcohol dependent individuals. Use of DEXA scan and Oxygraph to analyze net effects of the NT is my main purpose for current project.
