Teaches Chemistry and Environmental courses including Principles of Chemistry I and II labs and recitations, and Ecology and the Environmental Challenge.
Scholarly interests – biogeochemistry in marine sediments, environmental controls on microbial processes, greenhouse gas production in marine/freshwater environments.
Johanna Maltby has supervised multiple undergraduates and advised them during laboratory work, field trips, data analysis, and thesis writing. Her main research interests include biogeochemical processes in aquatic systems; specifically, she focuses on the effect of oxygen and temperature on microbial greenhouse gas production. Her hobbies include enjoying Maine’s unique nature through biking and hiking.
