Student Volunteer Program

If you are a student wanting to attend ESUG, have you considered being a student volunteer? Student volunteers help keep the conference running smoothly; in return, they have free accommodations, while still having most of the time to enjoy the conference. More information. From last year, ESUG is co-locating the isLoop summer school for student volunteers during the weekend before the conference.

You can support the ESUG conference in many different ways:

  • Sponsor the conference by our sponsoring packages
  • Submit a talk, a software or a paper to one of the events. See below.
  • Attend the conference. We'd like to beat the previous record of attendance.

Thanks to our sponsors, students can get free registration and hosting if they enroll into the Student Volunteers program.
