Important message to all incoming/outgoing ERASMUS students: in case you need any (of the many…) signatures from me, the best way to reach me is during my office hours (see above). In straightforward cases, you can also drop the form in the LS11-office (Frau Jankord, room 239), where I'll then leave the signed copy for pickup (usually after a couple of days). Please fill in all forms correctly and completely before giving them to me.
