This is SIYSS


Stockholm International Youth Science Seminar is an annual event in which 25 of the world’s foremost young scientists are invited to take part in a unique science and culture program between the 7th and 11th of December. All participants are between the ages of 18-25 and have been selected at international science fairs and by top ranking universities based on their extraordinary research efforts.

Unfortunately SIYSS 2021 is canceled due to the ongoing pandemic. There are simply to many uncertainties to go through with SIYSS this year.

Last year, we were able to pull off a successful digital SIYSS with interesting new events together with Nobel Laureate Donna Strickland and many others. Perhaps they will play an important role in the future of SIYSS. Just because it is cancelled, we will not stop working. Now, we aim to develop and prepare for an amazing SIYSS in 2022.

If you are a teacher, check out SIYSS school material, containing abstract, poster, presentation practicing and more.
Almost everything from SIYSS 2019 and 2020 is available to use whenever it suits your teaching plan.
