Research

My research focuses on diet and physiological changes in the Pacific walrus (Odobenus rosmarus divergens) throughout the past 2,500 years which includes current and past climate cooling and warming events. Specifically, I am looking at steroid hormone concentrations (physiological; e.g. cortisol, progesterone, estradiol, and testosterone) and stable isotopes ratios (diet; carbon and nitrogen) in archaeological, historical, and modern bone and teeth samples covering a time frame of 2,500 years. Results from this study will give management programs an insight into how resilient the Pacific walrus, an important subsistence marine mammal for Native Alaskans, is to the current warming in the Arctic based on their response to similar past climate warming events.
