A theoretical nuclear physicist working on effective field theory descriptions of nuclear forces. His review with Evgeny Epelbaum and Ulf-G. Meißner compares descriptions at different resolution scales. Selecting the relevant low-energy degrees of freedom permits controlled calculations of few-nucleon systems while retaining constraints from quantum chromodynamics.[ref]
