Aaron is an aquatic ecologist primarily interested in the fate and importance of different sources of primary productivity in lakes, estuaries, and the ocean. Aaron’s PhD research focused on the role of seaweeds as an energy source for deep subtidal food webs. For his postdocs, Aaron worked on quantitative modeling of lake zooplankton diet using fatty acid biomarkers (Kankaala Lab, Finland), a meta-analysis investigating environmental and phylogenetic drivers of phytoplankton lipids (Winder Lab, Sweden), and synthesis work on the under-ice ecology of lakes (Hampton Lab, Washington). Aaron uses a combination of observational and experimental approaches to study trophic interactions, with a particular emphasis on fatty acids as both biomarkers and as limiting nutrients for invertebrate consumers. Aaron’s other academic interests include student mentoring, natural resource management, terrestrial wildlife ecology, and citizen science.

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 Galloway lab will have the facilities for extraction and analyses of lipid biomarkers on the OIMB campus. Galloway’s current research interests include subtidal kelp forest ecology, macroalgae-derived energy subsidies, arctic ice-algae benthic-pelagic coupling, and experimental feeding trials designed for improving quantitative biomarker mixing model analyses.
