Trace gas biogeochemistry – The Jiao Group

TThe Jiao group investigates the sources, sinks, transformations, and impacts of climate-relevant gases, including reactive volatile compounds, greenhouse gases. Combining field observations, laboratory experiments, and modeling, we study how environmental change and ecosystem properties influence land-air exchange, from plot to landscape to global scale, advancing understanding of Earth’s biogeochemical cycles.

 

 

 

 

 

Our work addresses the production, consumption, and atmospheric fate of trace gases such as biogenic volatile organic compounds, reactive nitrogen, halogen- and sulfur- containing gases, etc. We explore how climate change, biological activity, and abiotic factors shape gas fluxes, and how these processes scale from local ecosystems to the global atmosphere.

 

 

  • Reactive trace gas flux measurements and modeling
  • Soil–atmosphere and water–atmosphere bidirectional exchange processes
  • Stable isotope and molecular tracing of gas metabolic pathways
  • Scaling gas exchange processes from plot to landscape to globe
  • Climate change effects on ecosystem–atmosphere interactions

We welcome MSc thesis projects, Bachelor students, and visiting scholars interested in biogeochemical cycles and climate change. Projects can involve laboratory experiments, data analysis, or field work, and may include trips to high-latitude ecosystems such as northern Scandinavia. Opportunities for research assistant, PhD and postdoctoral positions depend on funding availability and will be announced on the PI’s and VOLT center’s social media channels (LinkedIn, Bluesky, X/Twitter) if open.
