Wolfgang office: room 906 (9th floor), Huygens Laboratory

Office hours

Also because of the tight lecture schedule in Leiden, Wolfgang doesn't have regular office hours - simply send a brief informal email when you want to meet me (probably check my agenda) and we'll manage! Or drop by on the 9th floor Huygens between 12:30 and 13:30, then we usually have lunch.


Note: Due to construction work, the public entrances to the Huygens building are hard to find, please call us or ask someone!
