EXPAND Kickoff Conference

Date

June 1 — 3, 2026

Agenda

The focus of the EXPAND kickoff conference will be on introducing and discussing the key scientific questions and opportunities for collaboration. There will be focused sessions for each working group featuring a few presentations and plenty of time for discussion and networking. Participants will also have the opportunity to present posters, which will be up for the entire duration of the conference.

Practical Information

Accommodation

We don't have a hotel block reservation, but the Lisbon Academy of Sciences is in a very central and walkable area with many hotel and Airbnb options.

Reimbursement

Funded participants can submit reimbursement claims: €150 of daily allowance and up to €500 for transportation expenses. This transport limit may be reviewed in justified cases under the meeting budget conditions.

  • Participants have 15 days after the end of the event to submit their reimbursement claim.
  • Claims must be submitted through the e-COST platform only.
  • Please ensure that your travel tickets by flight or train (invoice + booking confirmation) clearly show your name, departure and arrival times, destinations, the corresponding amount paid, and the service provider.
  • Travel cancellation insurance should be encoded separately from the flight ticket, under “travel - plane”.
  • Car travel (for long-distance travel of 101-1000 km): justify with a parking receipt only.
  • For the reimbursement process, our accounting department will require your VAT number or equivalent tax identification number. Please include it in the “Additional info” section of your e-COST claim.
  • Finally, please remember to sign the attendance lists during the event — these are essential for calculating the daily allowance.
