My research is in theoretical atomic physics, especially high-precision quantum electrodynamic calculations in light atoms and exotic atomic systems. I study energy levels, fine and hyperfine structure, recoil and nuclear-structure effects, and related questions where accurate theory can be compared with precision measurements.

These calculations contribute to tests of bound-state QED, searches for possible deviations from the Standard Model, and the determination of fundamental constants and nuclear properties.

• Quantum electrodynamic corrections to spectra of light atoms
• Fine and hyperfine structure in few-body atomic systems
• Recoil, finite nuclear size, and nuclear structure effects
• Exotic systems such as muonic hydrogen, muonium, positronium, and antiprotonic atoms
• High-precision comparison between theory and experiment

Teaching details

Teaching in SIS

I supervise bachelor's, master's, and doctoral theses in theoretical atomic physics. I offer topics related to precise calculations of energy levels in light atoms, quantum electrodynamic corrections, and numerical methods for few-body atomic systems.

Students interested in theoretical atomic physics are welcome to contact me by email. A good starting point is curiosity about quantum mechanics, mathematical methods, and careful analytical or numerical calculation.
