We discuss in detail a method to study transverse momentum dependent parton distribution functions (TMDs) using lattice QCD. To develop the formalism and to obtain first numerical results, we directly implement a bilocal quark-quark operator connected by a straight Wilson line, allowing us to study T-even, "process-independent'' TMDs. Beyond results for x-integrated TMDs and quark densities, we present a study of correlations in x and k(perpendicular to). Our calculations are based on domain wall valence quark propagators by the LHP Collaboration calculated on top of gauge configurations provided by the MILC Collaboration with N-f = 2 + 1 asqtad-improved staggered sea quarks.
