Emma Johnson

PhD Candidate
Department of Earth and Environmental Sciences

I joined the Cory lab in 2023 as a PhD student studying reactive oxygen species, specifically hydrogen peroxide (H2O2), in harmful algal blooms (HABs) on Lake Erie. I am interested in the role lake sediments play in the concentrations and fluxes of H2O2 in the water column and how this may affect the toxicity of HABs. Prior to joining the Cory lab, I earned my B.S. in Geological Sciences from the University of Southern California, where my undergraduate research pertained to carbon in coastal urban environments and marine sediments, as well as trace metals in coastal waters.
