July-September 2021: Visit of Mr. Marko Wojtkowiak

We welcome Marko Wojtkowiak. Marko joins our group for 6 weeks as internship student from University College, London.

About us

Our group is part of the Saarland University, located in Saarbrücken, Germany. Saarbrücken is a major city of the SaarLorLux region, and capital of the German state of Saarland. It has become a renowned centre of science, hosting several universities and research institutes and facilities (the Saarland University, the University of Applied Sciences, two Max Planck Institutes - just to name a few), giving it the flavor of a typical university and research town.

More information about the city can be found at the city's official website (also in French, and German).

How to get here

By train:

Saarbrücken is connected to the Deutsche Bahn's (German Railways) ICE and IC/EC high-speed network. Saarbrücken Central Station [Saarbrücken Hbf - Hauptbahnhof] runs several daily services to Paris and Frankfurt (less than 2 hours long), and to other cities in eastern France (Metz, Strasbourg, Nancy), western/southern Germany (Kaiserslautern, Trier, Mainz, Mannheim, Karlsruhe), and Luxembourg.

For more information see the Deutsche Bahn website.

By plane:

  • The Saarbrücken-Ensheim Airport (SCN) is about 15 km / 9 mi from the city center. From there the city center can be reached by local bus (the R 10 line) or simply by taxi.
  • The Frankfurt Airport (FRA) (the biggest airport in Germany, located in Frankfurt am Main), is about 170 km / 105 mi from Saarbrücken. Using public transportation, it is a direct trip (approx. 2 hours) by train from the Frankfurt Airport Regional Station [Frankfurt (Main) Flughafen Regionalbahnhof] to the Saarbrücken Central Station.
  • The Luxembourg Findel Airport (LUX) is about 100 km / 62 mi from Saarbrücken. It is possible to reach Saarbrücken via Luxembourg's Central Station [Luxembourg Gare Centrale], which can be reached by a frequent 25-minute bus ride. Then there are several trains serving Saarbrücken, although at the moment the most convenient way is to take a bus: a 1h 15min direct trip to Saarbrücken Hbf.
  • Paris two major airports, Roissy/Charles de Gaulle (CDG) and Orly (ORY), are well connected to the Parisian public transport network by metro and bus (more information can be found in the Airports of Paris website). It is possible to reach Paris Est/Gare de l'Est, the SNCF train station where the trains to/from Saarbrücken depart/arrive, in approx. one hour. Then it is a two-hour straight trip by train.
  • The Frankfurt-Hahn Airport (HNN) is about 110 km / 69 mi from Saarbrücken. Using public transportation, currently it is only possible to reach Saarbrücken from there taking a service bus to a nearby city (Trier, Idar-Oberstein or Mannheim) and then catching a train to the Saarbrücken Central Station. More information here.
 

Local transportation - How to get to the university

The city of Saarbrücken is served by a comprehensive network of public transportation. If you are trying to reach the main campus of Saarland University, you can do so by local bus. The three bus stops (Haltestelle) on campus are Universität Campus, Universität Mensa, and Universität busterminal.

  • If you are coming from Saarbrücken Central Station, you can take the buses 102, 112 and 124 from the Saarbrücken Hbf bus stop.
  • If you are coming from University Guest Houses on the East part of town (on Hasseler Weg or Kaiserslauterner Straße), you can take the line 136 from the bus stops Stadion Kieselhumes or Zweibrücker Straße.
  • If you are coming from the University Guest Houses or the hotels in the city center, you can take the buses 101, 102, 109, 111 (typically from the bus stops Johanneskirche and Haus der Zukunft), and 112, 124 (from Haus der Zukunft).
  • If you are coming from the Dudweiler area, you can take the buses 101, 102, 136, 138 and 163 - typically from the Hermann Löns Straße bus stop.

Here you can download a map of the city with further information (~5Mb). Here you can check the bus schedule and get further information on the SaarBahn&Bus serving Saarbrücken. Here you can download a complete map with all the SaarBahn&Bus lines (~10Mb). If you have trouble downloading this file, please try also downloading the Liniennetz-Plan file here.

How to find us!

Our offices are located in the East area of the main (Saarbrücker) campus (buildings E2), more precisely in the E2.6 building (Gebäude E2.6). Here you can find an interactive map (Interaktiver Lageplan des Saarbrücker Campus) of the university campus, and here you can download a map with further indications to reach us.
