Jens Boos

Jens Boos is a Young Investigator Group Fellow leading the Black Hole Phenomenology Group at the Institute for Theoretical Physics, Department of Physics, Karlsruhe Institute of Technology (KIT). His research bridges observational black hole data with fundamental physics models, focusing on new particles and gravitational theories beyond general relativity. Previously, he held postdoctoral positions at William & Mary (2020-2023) and completed his PhD at the University of Alberta (2016-2020).

His academic journey includes:

• PhD in Physics, University of Alberta (2016-2020), supervised by Valeri P. Frolov and Don N. Page
• Perimeter Scholars International program, Perimeter Institute for Theoretical Physics (2015-2016)
• Master of Science, University of Cologne (2012-2015), thesis on BTZ black hole quasi-normal modes under Friedrich W. Hehl and Claus Kiefer

Boos specializes in analytical approaches to three core research pillars: non-singular black hole models (studying light propagation in singularity-free spacetimes), strong first-order phase transitions in the early universe (modeling gravitational wave signatures), and post-Riemannian gravity (exploring theories with torsion and curvature beyond standard geometry). His work connects quantum gravity effects to observable phenomena in gravitational wave astronomy and black hole imaging, with emphasis on mathematical rigor and testable predictions.

Publications since 2015 reveal an evolving trajectory from foundational work on exact solutions in general relativity toward contemporary focus on nonlocal gravity phenomenology. Recent output emphasizes ultraviolet regulators in quantum gravity, resonant particle production mechanisms, and mathematical structures in black hole spacetimes—demonstrating consistent integration of differential geometry, quantum field theory, and astrophysical observables.

Key recognitions include:

• Vanier Scholar (premier Canadian doctoral award)
• University of Alberta Faculty of Science Dissertation Award
• DTP/WITP P.R. Wallace Thesis Prize from the Canadian Association of Physicists

As group leader, Boos currently supervises master's student Hao Hu and bachelor students Felix Wunsch and Marek Hartenfels. While unavailable for PhD/master thesis supervision per his current mandate, he actively recruits bachelor researchers. His KIT-funded Young Investigator Group supports analytical model development for gravitational wave data interpretation, with particular attention to extreme mass-ratio inspirals. The group maintains strong international collaborations with institutions including William & Mary and the University of Alberta.

The Black Hole Phenomenology Group operates as a hub for mathematical physics innovation, combining expertise in gauge theories, nonlocal operators, and cosmological phase transitions to probe quantum gravity signatures in astrophysical data. Current projects include kilometer-scale UV regulator phenomenology and topological defect analysis in nonlocal gravity frameworks.
