Research interests

General interest in Quantum Field Theory. In particular Quantum Chromodynamics (QCD), and large-order behaviour of the perturbation series in QCD. Recent attempts to improve determination of the strong coupling from experimental data using renormalon techniques. A related interest is the so-called scheme dependence problem in QCD, in particular the avoidance of renormalization scale dependence, which is also crucial for reliable strong coupling measurements. I am also interested as a sideline in Supersymmetric Quantum Mechanics.
