21-30 September 2021
Online Conference
Europe/Berlin timezone


CYSS2021 will happen entirely virtual. The main sessions will be held via Zoom for which all registered participants will receive a separate invitation via Email. You can present your talks in any way you like as long as it is possible by screen-sharing over Zoom.

Additionally we will offer a self-hosted (so all your data and messages are safe) chat service based on Mattermost. All registered participants will receive an invitation to that as well. Here you can connect with the presenters and your peers and also ask questions which maybe you could not ask directly after the presentation. We encourage all presenters to look at the chatrooms and answer question after their talks. It also features integration into Zoom, so if you want to have a more personal contact with any of the participants, it's just a click away.

Plenary Sessions

We will host eight plenary sessions over the course of four days on Zoom. You can see our up-to-date timetable here. Each session will be introduced by an invited speaker, followed by several contributed talks from junior researchers.

You will receive the login credentials shortly before the first day of the conference. We kindly ask you to not take audio or video recordings during the talks.

Poster Sessions

We will host two poster sessions in total, on September 23 14:00 CEST and on September 28 18:00 CEST. Each poster presenter is asked to upload their poster in advance. The preferred poster format is 16:9 with a minimum resolution of 1920 px × 1080 px. We will provide templates in case you do not want to build your own.

The poster sessions will be a combination of text-based and video chat using our Mattermost platform as well as a video chat service (most probably Zoom). All poster presenters should have audio equipment and, ideally, also a webcam.

Scientific Speed Dating

At CYSS2021, we will for the first time test a new format. The biggest concern about online conferences is the lack of networking. We have put a lot of thought into this and come up with a Scientific Speed Dating session. Here, you will have the chance to meet other CYSS participants in an informal setting and talk - we will provide some icebreakers and after that, it's up to you. From discussing your research and finding exciting new possibilities for collaboration to just getting to know one another over a cup of coffee, anything goes!

The format is simple: We will distribute you over several breakout rooms with up to five participants per room. You then have 15 minutes to get to know one another. Ideally, you should be prepared to present yourself and your research interests in about 1-2 minutes, but there will also be informal icebreaker questions to keep the conversation moving. The groups will not be ordered according to field of research, so be prepared to explain your synthetic work so that even a theoretician will understand it (and vice versa)! After 15 minutes, we will reshuffle the rooms and you will then be in a new breakout room with new partners. We will repeat this roughly four or five times in total.

The Speed Dating session is explicitly open for researchers at all career stages and also undergrad students are encouraged to join and discuss their interests with more senior researchers. The entire session will take place on Zoom, so all participants will need audio (and ideally video) equipment.

To participate, we kindly ask you to check the respective box at your registration, so we know how many people will roughly participate. You can always change this later under the Registration tab on the website.
