Jesper Liengaard Johansen

Jesper Liengaard Johansen holds dual appointments at the University of Copenhagen as a Postdoc in the Department of Plant and Environmental Sciences (Section for Plant and Soil Sciences) and as an Assistant Professor in the Department of Biology (Terrestrial Ecology). His research bridges soil science and plant ecology with a strong focus on environmental contaminants and sustainable agricultural practices.

Dr. Johansen's research interests center on soil-plant-microbe interactions under environmental stress conditions. His work examines how pollutants like cadmium and microplastics affect soil ecosystems, and how biological and chemical interventions can mitigate these effects. He investigates the impacts of alternative fertilization methods including wood ash, human urine, and recycled waste products on soil health and plant growth.

Analysis of his recent publications (2020-2024) reveals consistent work in environmental soil science with increasing focus on microplastic pollution and advanced waste recycling techniques. His research employs both field experiments (notably the long-term CRUCIAL experiment) and controlled laboratory studies, often examining microbial community responses to environmental stressors. The interdisciplinary nature of his work spans soil chemistry, plant physiology, and microbial ecology.

Dr. Johansen maintains active collaborations with researchers including Vestergård, Ekelund, Kjøller, and Magid across multiple projects. His work appears in high-impact journals such as TrAC - Trends in Analytical Chemistry, Science of the Total Environment, and Environmental and Experimental Botany, demonstrating both methodological innovation and ecological relevance.
