Rea Hall

Dr. Rea Hall is a researcher at the University of Natural Resources and Life Sciences, Vienna (BOKU), affiliated with the Institute of Botany and the Institute of Crop Production within the Department of Agricultural Sciences. Based at the Experimental Farm Groß-Enzersdorf, she conducts research on invasive plant species, particularly common ragweed (Ambrosia artemisiifolia) and Ambrosia psilostachya, focusing on weed management, seed viability, and plant competition in agricultural systems.

Her research interests center on invasive plant ecology, weed science, and agroecology, with a strong emphasis on understanding how invasive species impact crop productivity and ecosystem dynamics. She investigates seed longevity, germination behavior, and the biochemical mechanisms behind plant competition, especially the disruption of symbiotic nitrogen fixation in legumes by ragweed. Her work integrates field experiments, genetic analysis, and ecological modeling to develop sustainable management strategies.

The trends in her most recent publications reveal a consistent focus on the ecological and agricultural impacts of ragweed species, including their genetic structure, seed bank persistence, and interference with crops like soybean. Her studies often involve multi-site collaborations across Europe and contribute to both scientific understanding and practical weed control solutions.

Dr. Hall has contributed to several research projects funded by the EU, Austrian Academy of Sciences, and regional bodies, primarily investigating ragweed control and invasive species management. She has supervised at least one master’s thesis and regularly presents her findings at international conferences.

She is actively involved in knowledge transfer, publishing both scientific papers and popular science articles in journals such as Die Landwirtschaft and Unser Land, helping bridge the gap between research and agricultural practice.
