Several people who planned to attend and present their work at ATTO were in the end unable to travel. For those who fall within this category, we offered the option of following the oral sessions live on Zoom, and of submitting their presentations as recordings which could be viewed online by the conference attendees. Please click the links below to find the recordings of their presentations. The links will also be accessible as QR codes which can be found at the location of the poster during the poster sessions.
