Loeka Jongejans

Dr. Loeka Jongejans serves as a Research Associate in the Earth and Climate department within the Faculty of Science at Vrije Universiteit Amsterdam. With an active research profile evidenced by multiple publications in 2025, Dr. Jongejans contributes significantly to understanding critical climate change processes in Arctic environments.

Her research expertise spans several interconnected domains:

• Permafrost carbon dynamics and greenhouse gas emissions
• Arctic ecosystem responses to climate change
• Thermokarst formation and its environmental consequences
• Biogeochemical cycling in frozen environments
• Interactions between terrestrial and marine systems in the Arctic

Analysis of recent publications reveals a strong emphasis on quantifying carbon and nitrogen cycling in thawing permafrost regions, with particular attention to greenhouse gas production mechanisms and the fate of organic matter during environmental transitions. The research demonstrates sophisticated methodological approaches including lipid biomarker analysis and mineral-organic association studies.

Dr. Jongejans maintains active international collaborations across multiple institutions, contributing to significant research efforts examining permafrost vulnerability in Siberia and developing innovative citizen science tools for environmental monitoring. Her work provides essential data for climate models predicting Arctic feedback mechanisms to global warming.
