Thomas Gregov is a researcher in computational glaciology, working at the intersection of applied mathematics, fluid dynamics, and scientific computing. His research focuses on marine ice-sheet dynamics, with particular interest in basal friction, subglacial hydrology, and Antarctic contributions to future sea-level rise.
He obtained his Master’s degree in Engineering Physics from ULiège, Belgium, in 2020, where he specialized in computational mechanics and scientific computing. He then completed a joint PhD in Glaciology at ULB and in Engineering at ULiège, still in Belgium, in 2025. His doctoral research investigated how subglacial conditions influence the dynamics and stability of marine ice sheets, combining analytical and computational methods to study basal friction, subglacial hydrology, and ice-flow dynamics.
Thomas is now a postdoctoral researcher in the ICE group at the University of Lausanne, where he works on the SNF-funded PINNACLE project in collaboration with the University of Zurich. His current work focuses on scientific machine learning for accelerating ice-flow computations, with the goal of extending the Instructed Glacier Model to ice shelves and marine ice sheets. This work aims to help provide the glaciology community with an open-source, computationally efficient ice-sheet model and to reduce uncertainties in projections of future sea-level rise from Antarctica and Greenland.
