Summary: In this thesis we develop a way of examining the Stokes structure of certain irregular singular \(\mathcal{D}\)-modules, namely the direct image of exponentially twisted meromorphic connections with regular singularities, in a topological point of view. We use this topological description to compute linear Stokes data for an explicit example.
