Perturbative Quantum Chromodynamics:  hyperasymptotics, transseries and the origin of quark-hadron duality violation; quark-hadron duality violation from models of hadron resonances;  testing duality violation with functional analysis; improved perturbative series;  conformal mappings of the Borel plane; determination of the strong coupling  from hadronic decays of the tau lepton

Precision predictions in hadron physics: charge radius of the pion,  constraints on the parameters of effective theories, mass and width of the lowest resonance in QCD

Precision tests of the standard model: low-energy hadronic contribution to muon magnetic anomaly, onset of perturbative QCD for exclusive observables

Flavour physics: model-independent constraints on quark masses; model-independent parametrizations of semileptonic form factors; determination of the CKM matrix elements

Physics beyond standard model and LHC physics
