The full program booklet is only available online this year. If you would like to have a paper copy of any pages of the booklet you will need to print them yourself.
The main site for the conference is Otakaari 1, the Aalto University Undergraduate Centre. Copies of the map of the building layout will be posted during the conference.
Clicking on a talk title in the schedule below will take you to the corresponding paper in the Bridges Archive.
Talks marked with π will be delivered remotely and have an in-person Chair. Six sessions include remote talks and these are scheduled in Room A. For in-person sessions the Chair is denoted in the schedule.
All times are given in EEST (GMT+3). If you are participating remotely and plan to watch Room A presentations (including plenary talks), please convert to your local time zone carefully. It may help to use an online tool like timeanddate.com. Recordings of Room A talks will also be available during the conference. All conference participants registered in any category will have access to online talks. Registered participants should have received an email from Sujan Shrestha on July 20 with directions for accessing the remote content. Only talks in Room A will be available remotely.
