Research Interests:

My research interests mainly comprise:

a) the physics of the strong interaction from the low to the  high energy regime.

b) the quark and gluon (spin) structure of hadrons (most notably of the nucleon) as expressed through different kinds of parton distributions.

c) form factors of the nucleon.

d) single spin asymmetries in hard scattering processes.

e) partonic structure of hadrons beyond the collinear approximation.

f) QCD-factorization and universality of parton correlation functions.
