معرفی
Christian von Sperber is an Associate Professor in the Department of Geography at McGill University, where he teaches courses including Environmental Systems (GEOG 203), Soils and Environment (GEOG 305), and Global Biogeochemistry (GEOG 505). His research focuses on biogeochemical processes in terrestrial ecosystems, with particular emphasis on phosphorus and nitrogen cycling in soils.
His educational background includes:
- PhD in Environmental Science from ETH Zurich, Switzerland (2014)
- Postdoctoral research in the Department of Biology at Stanford University, USA (2014-2016)
- Senior Scientist position at the Department of Agricultural Sciences, University of Bonn, Germany (2016-2018)
Dr. von Sperber's research employs stable isotope techniques to investigate nutrient dynamics in soil-plant systems and aquatic ecosystems. He is particularly known for his work on the oxygen isotope composition of phosphates as a tracer for phosphorus cycling. His studies address critical environmental issues such as the impact of land-use changes on soil nutrient pools and the role of riparian buffer zones in reducing phosphorus runoff into waterways.
His recent publications reveal a strong focus on methodological advancements in tracing phosphorus through isotopic and spectroscopic approaches. These studies span diverse environments from forest ecosystems to agricultural landscapes and groundwater systems, highlighting the interconnectedness of terrestrial and aquatic nutrient cycles.
