Dr Lukas Hallberg is a Research Fellow in the School of Geography, Earth and Environmental Sciences at the University of Birmingham. He holds a PhD in Soil Science with a specialisation in Agricultural Water Management from the Swedish University of Agricultural Sciences, awarded in 2024. His doctoral thesis examined floodplain remediation in agricultural streams to improve process understanding for reduced eutrophication. He also earned an MSc in Agricultural Sciences and an MSc in Biology from the same institution in 2019, along with a BSc in Biology completed in 2017.
Dr Hallberg is a catchment researcher whose work centres on riparian processes and their effects on water quality and climate. His current research examines carbon cycling and flood attenuation in streams influenced by ecosystem engineers. Recent publications include the 2026 article “Beavers can convert stream corridors to persistent carbon sinks” in Communications Earth and Environment and the 2024 paper “Seasonal Variation in Flow and Metabolic Activity Drive Nitrate and Carbon Supply and Demand in a Temperate Agricultural Stream” in the Journal of Geophysical Research: Biogeosciences. His contributions advance understanding of stream corridor dynamics, nutrient cycling, and responses to environmental change in temperate agricultural and riparian systems.
