PhD Position in Geography (VU University of Amsterdam)

Institution: Vrije Universiteit Amsterdam, Earth Sciences Department Location: Amsterdam, Netherlands Start Date: April 2026 (or as early as possible thereafter) Duration: 4 years (funding secured) Employment: Minimum 0.8 FTE, initially 1-year contract with extension to complete PhD Your Function We invite applications for a PhD position in the 5-year PeTCaT research project funded by the Schmidt Sciences Foundation. The PeTCaT project (“Rapid Permafrost Thaw Carbon Trajectories”) aims to quantify the effects of permafrost thawing on the global carbon cycle. Current Earth system models used for future climate projections inadequately represent permafrost thaw processes and associated climate feedbacks. A key shortcoming is that models often do not account for rapid thaw processes common in ice-rich Arctic permafrost regions. The goal of this PhD project is to advance the modeling of rapid thawing processes. This includes: Development and application of the CryoGridLite process-based land surface model Investigation of ground ice dynamics and rapid thawing processes (e.g., thermokarst, thermo-erosion, thaw slumps, ice-wedge degradation) Integration of process-based modeling with data-driven approaches (e.g., machine learning, simulation-based inference) using geospatial data Application of the modeling framework to retrace pan-Arctic permafrost evolution over the last millennia and improve projections of future thaw trajectories relevant to permafrost carbon emissions and climate feedbacks The project will be conducted in close cooperation with the Alfred Wegener Institute (Germany) and other international partners in Germany, Sweden, Canada, and the USA. Fieldwork opportunities in permafrost regions of Canada and/or Alaska are part of the project.
