معرفی
Professor Penny Johnes is a Professor of Biogeochemistry at the University of Bristol's School of Geographical Sciences. Her research focuses on nutrient cycling, dissolved organic matter (DOM), and phosphorus management in freshwater ecosystems, with applications to agricultural and environmental policy. She has collaborated extensively with experts in earth sciences, chemistry, and environmental management.
Her work addresses critical issues such as water quality monitoring, the impact of land use on DOM composition, and the mitigation of agricultural pollution. Recent studies highlight her contributions to understanding phosphorus dynamics in aquifers, microbial responses to peatland degradation, and the ecological implications of DOM signatures across diverse landscapes.
Dr. Johnes has advised on policy initiatives like the Nutrient Management Expert Group (NMEG) report, emphasizing sustainable agricultural practices. Her research integrates cutting-edge analytical techniques, including mass spectrometry and isotope probing, to advance biogeochemical insights.
Key collaborations include projects with Dr. Heather Buss (Biogeochemical Weathering), Dr. Charlotte Lloyd (Royal Society Fellow in Geographical Sciences), and Prof. Richard Evershed (Chemistry). Her work bridges laboratory analysis, field studies, and policy-oriented research to tackle global environmental challenges.
