Welcome to Luxembourg

The Network Science and Economics Conference brings together economists, computer scientists, and applied mathematicians working on networks — how they form, what flows through them, and how they shape markets, institutions, and behavior.

In 2026, the conference series comes to Europe for the first time. We are delighted to welcome the network science and economics community to the University of Luxembourg for three days of plenary talks, contributed sessions, posters, and discussion.

The conference will take place in the Weicker Building on the Kirchberg plateau, with convenient direct tram connections to Luxembourg Airport, the city centre, and the main railway station.

At a glance

Three days of plenaries, contributed talks, and posters on the economics of networks.

Getting here

Transport is free

Arriving in Luxembourg

By air. Luxembourg Findel (LUX) is the country's only airport. The tram runs from the terminal across Kirchberg without a change — about fifteen minutes to the venue.

By rail. TGV InOui runs direct from Paris Gare de l'Est in a little over two hours, calling at Metz. There are direct services from Brussels and from Trier. From Luxembourg Gare Centrale, take the tram towards the airport and get off at Alphonse Weicker.

Getting around

Public transport is free. Since 2020, buses, trams and second-class trains have been free of charge throughout Luxembourg, for residents and visitors alike. There is no ticket to buy and nothing to validate — you simply get on.

The tram. A single line runs from the airport across the Kirchberg plateau to Gare Centrale and on towards the stadium, so the venue, the hotels, the station and the airport all sit on the same route.

Conference accommodation

Rates now closed

The negotiated conference rates have all expired. The partner hotels may still have rooms at their public rates, and Visit Luxembourg lists other options across the city.

How to book: open the conference booking page and reserve directly. It opens on double occupancy, so change it to single occupancy if you are travelling alone.

Around the city

Beyond the conference

Luxembourg is one of Europe's smallest countries, bordered by Belgium, France and Germany. Most of it is rural: Ardennes forest and nature parks in the north, sandstone gorges in the Mullerthal to the east, vineyards along the Moselle in the southeast. The capital grew up around a medieval fortress on the cliffs above the Alzette, and its old town is a UNESCO World Heritage site, fifteen minutes from the venue by tram.

Further afield

Direct trains

Direct trains run from Luxembourg Gare Centrale into Belgium, France and Germany, so a day either side of the conference is easy to use.

Direct rail connections from Luxembourg Luxembourg Gare Centrale has direct trains to Trier in about 50 minutes, Metz in about 50 minutes, Paris in about 2 hours 15, and Brussels in about 3 hours 20. LUXEMBOURG Gare Centrale Brussels ≈3 h 20 Trier ≈50 min Metz ≈50 min Paris ≈2 h 15
Direct services only, times approximate. Distance from the centre shows journey time, not kilometres — which is why Paris sits closer than Brussels.
