PhD, Ecology- Colorado State University
BS, Ecosystem Science and Sustainability- Colorado State University
In The Fundamental & Applied Biogeochemistry Lab (aka The FAB Lab) we seek to do science that sits at the nexus of fundamental and applied ecology that benefits local communities. We do this through the lens of understanding biogeochemical fluxes at the ecosystem scale.
Aquatic biogeochemistry, sustainable aquaculture, microbial ecology, freshwater ecosystem ecology, nitrogen cycling and nutrient limitation, tropical and subtropical limnology, community driven research interests.
Coming Spring 2027- ECOL 2100- Global Climate Change: Past, Present, Future
As an ecosystem ecologist and biogeochemist, I study the interaction of local and global stressors on aquatic ecosystems. I am particularly interested in asking layered research questions where data can can simultaneously answer both fundamental ecological questions and applied questions with community impact.
