Hi! I am Maddie Armstrong (she/her)

Investigating the Evolution of Widespread Marine Invertebrate Systems in Response to Anthropogenic Change

I use ecological genomics to investigate adaptation despite high gene flow, studying how fine-scale environmental variation can result in genomic differences in widespread marine invertebrate species. My work also investigates specific physiological mechanisms to disentangle the evolutionary consequences of historical exposure to environmental conditions either short or long-term in the evolutionary history of a species.

Evolutionary Biologist · Postdoctoral Researcher

I am currently a post-doctoral researcher at the Lotterhos Lab, Northeastern University Marine Science Center. Broadly interested in adaptation to marine environments and genomic variation associated with environmental change, my current work focuses on evaluating genomic forecasting and machine learning algorithms to investigate differential success and the potential for adaptation in oysters across various environmental conditions. My doctoral research at UC Davis in the Bay Lab examined how urban stressors — pollution, population isolation, developmental disruption — alter the genomes of marine invertebrates, using the Pacific Purple sea urchin as a study system.

I am also deeply passionate about mentorship and science outreach. As a first-generation scientist who had to advocate for myself along the way, I want to help students figure out their career goals and achieve them with minimal hardship. I have been actively involved in the Evolution and Ecology Graduate School Preview Program at UC Davis, working to increase access and transparency to graduate programs and build diversity within these fields.
