معرفی
Professor Jan Kaiser is a Professor of Biogeochemistry at the University of East Anglia's School of Environmental Sciences, where he leads the Kaiser Lab focused on marine and atmospheric biogeochemistry. His research integrates chemistry, biology and physics to understand biogeochemical processes in the atmosphere and oceans.
His research interests include:
- Marine gases and isotopologues
- Nitrate aerosol isotopes
- Trace gas isotopologues
- Greenland and Antarctic firn air
- Lake nitrogen cycling
- Ocean gliders for biogeochemical observations
Professor Kaiser's laboratory develops high-precision analytical methods using isotope ratio mass spectrometers, cavity ring-down greenhouse gas analysers and ocean gliders. His most cited work involves the denitrifier method for triple oxygen isotope analysis of nitrate, which has become an important technique for studying nitrogen cycling in environmental systems.
His research has significant implications for understanding atmospheric chemistry, marine productivity, and the impact of human activities on greenhouse gas emissions. The lab offers analytical services for nitrogen and oxygen isotopic analyses of nitrate in freshwater and seawater samples.
Professor Kaiser has supervised numerous PhD students whose research spans polar snow chemistry, shelf sea productivity, marine observations using citizen scientists, and ocean carbon system monitoring. His work is supported by projects including EUROCHAMP-2020, NEEM, INTRAMIF, Arctic Lakes, GOPINA, and Pinch of Salt.
