Program
The program is still in development, and will be available from this page at a later date.
For some relevant information for your travel planning, click here.
In 2023, ALAN will consist of plenary sessions, parallel sessions, and poster sessions.
Talks will be mostly given in person in Calgary and will be streamed via Zoom. They can also be viewed on demand. All posters will be presented at a virtual poster session about two weeks prior to the conference and will be available online during the entire conference. Powerpoint and pre-recorded version must be prepared in advanced by an early date ASAP (see Registration section page for more details). Posters can additionally be presented in person during the main conference in Calgary.

- Invited plenary talks (25 min plus 5 min discussion)
- Contributed talks (15 min plus 5 min discussion)
- Poster sessions (Posters that will be physically presented at the conference should be printed in A0 portrait format (118.9cm x 84.1cm). Posters that will be presented only online do not have this requirement, but using a 16:9 or 4:3 aspect ratio means that the poster will display on the screen without the need for scrolling).
- There is a 100$ prize for the best poster by a young researcher (maximum 3 years past PhD). Poster judges are conference attendees selected by the steering committee, and the evaluation criteria are the design, ease of finding information, ability of presenter to explain the results orally, and the novelty of the results. Example: prize winner from 2021, 2020, 2018 and 2016.
- Elevator pitches (40 seconds): Poster presenters will be invited to make a pitch during the plenary sessions, with 40 seconds to advertise the highlights of his or her work. Posters will be on display during the whole conference, but presenters are asked to be present at their posters during their scheduled times
