Michael Ottman is a researcher in the laboratory of Dr. Brandy Toner at the University of Minnesota. The Toner lab focuses on understanding the biogeochemical processes driving iron, sulfur, and arsenic cycling in glacial aquifers in Minnesota. Michael’s work concentrates on sedimentary arsenic and investigating fungal remediation of mine effluent. His role on the Falkor for this expedition will be collecting and preserving samples for iron speciation analyses. Prior to joining the Toner lab, Michael’s undergraduate research looked at soil carbon sequestration and management. Michael holds a BS in environmental sciences from the University of Minnesota.
