Bio

My research is focused on trophic relationships between algae and creatures at the base of marine, estuarine, and lake food webs. I use fatty acids as biomarkers for questions about consumer resource use and lipid metabolism. My research questions are currently focused on kelp forest ecology, the role of seaweeds and detritus as a subsidizing energy source for subtidal food webs, the effects of coastal ocean acidification of juvenile Dungeness crabs, marine invertebrate trophic ecology (urchins, abalones, sea stars, isopods), and how host/parasite relationships affect trophic relationships. This work is taking place in projects throughout the NE Pacific (Alaska, British Columbia, Washington, and Oregon) and the Antarctic Peninsula.

Additional Information

The Galloway lab is generally focused on trophic inferences in aquatic food webs, with an emphasis on algae-invertebrate interactions. We use biomarkers such as lipids, fatty acids, and stable isotopes, paired with natural history, experimentation, and modeling. The Coastal Trophic Ecology Lab (CTELab) has facilities for extraction and analyses of lipid biomarkers on the OIMB campus.

For prospective graduate students:

I am not anticipating taking additional students in the fall of 2022. If something changes and I start recruiting a graduate student for a particular funded project I will post about it here and on my personal website, as well as through Twitter. With that said, I would be happy to hear from you if are looking for networking for future opportunities or if you are interested in collaborating on a funding proposal (e.g., NSF GRFP) that would help secure the funding you would need to go to grad school. I am always interested in networking with folks who are excited about trophic ecology, subtidal science (scientific diving) and fatty acids – particularly when there is an overlap with all of these areas. Please look at my statement of values on my personal website.
