Megan E Lewan
(she/her/hers)Megan Lewan is an Ann Arbor-based Great Lakes Biological Technician, specializing in water quality as it relates to benthic nutrient interactions.
At the Great Lakes Science Center as part of the Restoration and Conservation Science branch, Megan Lewan supports the ongoing Cladophora project as a scientific SCUBA diver, boat crew member, and data analyst. The Cladophora project aims to investigate drivers of the native alga's nuisance growth, importantly: phosphorus and other nutrient inputs, invasive mussel biomass, and light penetration.
