Activities

The Institute's scientific activities are centered around four to six main thematic programmes per year complemented by several workshops and individual lectures organized on short notice. Participation in thematic programmes and workshops is by invitation only.

To support the scientific education of graduate students and young researchers, the ESI regularly offers lecture courses at advanced graduate level held by so-called Senior Research Fellows. In addition, there are summer and winter schools in research areas of topical interest.

In 2012, the ESI has moreover initiated the Research in Teams programme offering individual visiting positions for teams of two to four researchers on application basis.

Since June 2016 the Junior Research Fellowship Programme supports external or local graduate students and recent postdocs.

For more information on the individual programmes and the application procedure, please select the activity you are interested in in the above menu.
