Sjors Jacco Heefer

Sjors Heefer is a lecturer at the Department of Mathematics and Computer Science at Eindhoven University of Technology. His research focuses on differential geometry and relativity theory, particularly pseudo-Finsler geometry and its applications to quantum gravity and modified theories of gravity. He is a member of the COST Action on quantum gravity phenomenology in the multi-messenger approach.

He holds a PhD from Eindhoven University of Technology (2018–2022), a Master’s from Radboud University Nijmegen (2015–2018), and a Bachelor’s from Radboud University Nijmegen (2012–2015). His work bridges mathematical rigor and physical applications, contributing to exact solutions in Finsler gravity and quantum gravity phenomenology.

Recent research trends include cosmological solutions in Finsler spacetimes, gravitational wave signatures in non-Riemannian geometries, and multi-messenger approaches to quantum gravity. He collaborates widely, contributing to white papers and reviews on quantum gravity phenomenology.
