My work focuses on precise quantum electrodynamic calculations of atomic spectra in light atoms. These systems are small enough for highly accurate theory, but rich enough to test our understanding of bound-state QED, nuclear structure, recoil effects, and the interaction between electrons and nuclei.
I am particularly interested in calculations that can be compared directly with high-precision experiments. Such comparisons make it possible to test the Standard Model in low-energy systems, search for possible new physical effects, and extract fundamental constants and nuclear properties.
Main topics
- Energy levels of hydrogen-like, helium-like, and other light atomic systems
- Fine and hyperfine structure
- Higher-order QED corrections
- Nuclear recoil and finite-size effects
- Nuclear structure effects
- Exotic atoms, including muonic hydrogen, muonium, positronium, and antiprotonic atoms
Research profile
The common thread is precision: developing theoretical calculations accurate enough to meet modern spectroscopic measurements and to make small physical effects visible.
