"I am part of a multi-disciplinary research team looking at why toxic-producing algal species are forming in Lake Erie. Specifically, we are exploring how hydrogen peroxide may be playing a role in allowing toxic algae to outcompete non-toxic algae. Hydrogen peroxide is an antimicrobial agent most people have in their medicine cabinets at home, but don’t realize that this chemical is also naturally produced in all waters on the earth, usually by processes involving sunlight."
