Dr. Paulsson's primary research interests center on uranium behavior in mining environments, mine water chemistry, pit lake ecosystems, and rock weathering processes. His work investigates how uranium is released from different rock types (particularly pegmatites containing uraninite) into mine waters, the role of groundwater in transporting uranium, and the geochemical factors controlling uranium mobility. He also studies pit lake systems, examining diel oxygen variations and testing remediation approaches like wood ash fertilization to stimulate algal growth and improve water quality.

Analysis of his recent publications reveals a strong emphasis on environmental geochemistry related to iron ore mining in Northern Sweden. His research combines field studies at active mine sites with laboratory analyses to understand element mobility, particularly uranium, which is classified as a river basin-specific pollutant in Sweden. Dr. Paulsson frequently collaborates with researchers from LKAB (the mining company) and other academics at Luleå University of Technology, with Lena Alakangas appearing as a regular co-author on his work.

While specific details about his teaching responsibilities aren't provided in the available information, his position as Associate Senior Lecturer indicates involvement in both research and instruction within the engineering programs. His work contributes significantly to developing better water management practices at mine sites and strategies to minimize contamination of downstream water bodies with radioactive elements.

Dr. Paulsson's research has practical applications for the mining industry, helping identify high-risk uranium sources before exposure during mining operations and informing site-specific management strategies to mitigate uranium contamination in recipient rivers and lakes. His publications in journals like Journal of Geochemical Exploration and Journal of Contaminant Hydrology demonstrate the scientific relevance and impact of his work in environmental geochemistry.
