Teaches Environmental and Marine Sciences and Chemistry courses including Climate Change & Glacial Geology, Oceanography, Principles of Chemistry I & II, and Research Science on Sebago Lake.

Scholarly interests -- "acid snow" deposition in the White Mountains, sedimentary geology, geologic history of northern South America and the Andes.

Johan Erikson's perspective as a geologist enables him to readily connect physical and chemical processes with natural examples. Field-centered education and research engage students, and strong conceptual and analytical capabilities empower students for science-based careers. He is currently researching acid-snow deposition on Mount Washington and investigating accumulation of high-density minerals in a variety of environments. Outside of work, Professor Erikson enjoys mountain climbing and Nordic ski racing.
