Erik Björn has been an associate professor and research group leader at the Department of Chemistry, Umeå University, Sweden since 2009. He received his Ph.D. in Analytical Science with emphasis in atomic spectroscopy from Umea University in 2002. His research focuses on trace metal speciation analysis and metal biogeochemistry. An important area of focus is the study of biogeochemical processes of mercury in aquatic and terrestrial ecosystems. The research program aims to both understand such processes at the molecular level and to establish their importance in natural environmental systems. To accomplish this, Dr. Bjorn’s group develops and implements new, powerful analytical methods and experimental strategies. Dr. Bjorn has produced over 90 articles and reports within these research fields and he has worked extensively with undergraduate teaching and public research dissemination. He currently serves as an Editorial Board Member for the journal International Journal of Environmental Research and Public Health. Dr. Björn has been main or co-advisor for approximately 20 Ph.D. students and Post Docs, and principal investigator for a dozen major external research projects.
