About the Program
Utrecht University invites applications for a fully funded PhD in Earth Sciences titled “Unravelling Clogging Mechanisms in Porous and Fractured Rocks” at the Department of Earth Sciences. This doctoral position focuses on quantifying how particle deposition, chemical precipitation and deformation-driven remobilisation influence fluid flow and clogging in geological formations. The project will be supervised by Dr Roberto Rizzo and aligns with the research theme of Sustainable Use of the Subsurface. The research duration is up to four years, based in Utrecht, Netherlands, with a likely start date of February 2026. The project offers advanced training using 4D micro-CT imaging, experimental flow-through cells, and numerical modelling, fostering international collaboration and professional development.
