Julian Sonner

The Department of Theoretical Physics at the University of Geneva is inviting applications for a postdoctoral researcher in the high energy physics group of Prof. Francesco Riva . The position begins in September 2027 and is offered for two years, with the possibility of a one-year extension. The research programme focuses on modern topics in theoretical particle physics and high energy physics, with particular interest in S-matrix theory , scattering amplitudes , bootstrap methods , energy correlators , and Hamiltonian truncation . The successful candidate will work within a group that engages with both formal theory and active methods used to probe fundamental interactions. The position sits in the Department of Theoretical Physics - Particle Physics, providing a research environment centered on collaborative work in theoretical high energy physics. The group also has close scientific ties with Prof. Julian Sonner , Prof. Denis Karateev , and Prof. Antonio Riotto , creating additional opportunities for exchange and collaboration across related areas.
