Ludda Ludwig

Graduate Students

Ludda joined the Department of Earth and Environmental Science PhD program in 2019. Her interests are scaling methane and carbon dioxide emissions, climate change impacts on Arctic carbon cycling through wildfires and permafrost thaw, and coupled biogeochemical cycling at terrestrial-aquatic interfaces. Ludda received her M.Sc. in Biological Sciences from the University of Alaska Fairbanks and B.A. in Biology, Chemistry, Mathematics, and Environmental Studies from St. Olaf College.


Ludda is investigating Hierarchical Scaling of Carbon Fluxes from Terrestrial-Aquatic Interfaces in the Arctic as part of her NASA FINESST fellowship.
