Biography

Erik Björn studies how the chemical structure of metal compounds controls mechanisms, kinetics, and reactions regarding central cycling of metals in the environment. His research focuses on chemical and biological processes involving trace metals and their interactions within ecosystems and biological systems, as well as industrial processes. He aims to develop new analytical techniques and experimental strategies to investigate chemical speciation, reaction mechanisms, and rates of trace metal compounds. A key area of focus includes studying biogeochemical processes involving mercury (Hg) in aquatic and terrestrial ecosystems. His research program seeks to understand these processes at the molecular level and establish their significance in natural environmental systems, utilizing advanced analytical methods and controlled model systems. Erik is committed to addressing the challenges related to trace metal research, particularly concerning mercury methylation and its implications for bioaccumulation in aquatic systems.
