Research Overview

I am interested in broad-scale marine mammal ecology. Feeding ecology in particular is a keystone piece of information to understand adaptation potential of marine mammals and challenges that may arise. Dietary limitations can affect reproductive success, compromise immune function, change exposure to new pathogens (i.e., parasites, contaminants), and can therefore not only limit marine mammal population growth, but also potentially introduce new threats to humans depending on them as a subsistence resource.

I focus my research on Arctic marine mammals, because (1) they are of cultural and nutritional importance to subsistence users, (2) the Arctic is undergoing noticeable change, and (3) planned oil and gas development in this habitat.

I am also working on a fish parasite, Ichthyophonus hoferi, in Chinook salmon, and its potential impact on pre-spawning mortality and fecundity.

 

Current research projects

  • Microplastics in northern fur seals on St. Paul Island
  • Microplastics in subsistence harvested bowhead whale tissues
  • Microplastics and phthalate concentrations in subsistence harvested Chukchi Sea beluga whales
  • Host and microbial contributions to wax ester lipid digestion in Arctic whales
  • Maternal transfer of microplastics across the placenta in subsistence harvested spotted seals
