Current Research Themes

Algal community composition and food web relationships on the Western Antarctic Peninsula (WAP)

 

This is a new NSF-funded project, starting in the spring of 2019. We'll be scuba diving from small boats deployed from the Laurence M. Gould, to explore the shallow subtidal zones and macroalgae of the WAP. Photo: Julie Schram

Effects of ocean acidification (OA) and food quality on the post-recruitment ecology of juvenile Dungeness crabs

Marine benthic invertebrate lipid metabolism

 

I am working on several projects, using an assortment of focal model organisms (urchins, isopods, crabs, gastropods), aimed at understanding the lipid metabolism and trophic transfer of dietary fatty acids to the tissues of invertebrates. How are 'trophic tracers' transferred to basal consumers? How does food quality and environment influence these processes? Photo: Reyn Yoshioka.

Kelp forest ecology and detrital subsidies

 

Kelp forests are dynamic ecosystems that create food and critical habitat. In parts of the Pacific coast, kelp forests are experiencing declines. I'm working in SE Alaska, British Colombia, the San Juan Islands, and Oregon to understand the importance of kelp as a trophic resource for herbivores such as urchins and abalone.
