Photon Day
To promote photo science at UU, the Center for Photo Science organizes The Photon Day! Prominent speakers are invited to give interesting talks as well as the winner of this year's "Uppsala Photon Science Award".
Photon Day 2022
The CPS would like to thank everyone for attending and participating in the Uppsala Photon Day 2022. The day began with a welcome reception followed by three talks by Håkan Rensmo, Ida Källquist and Sebastian Westenhoff related to photon science at Uppsala University. Following each presentation, we had engaging scientific questions from the audience. We would especially like to congratulate Ida Källquist as the winner of the Photon Science Award 2022.

Photon Day 2025
The Center for Photon Science at Uppsala University wants to give a huge thanks to everyone who joined Photon Day 2025! It was a great chance to explore the wide range of scientific research that relies on photon science, with three fascinating talks.
The day kicked off with an interesting talk from Edving Lungren about probing surface dynamics. Then, Agostino Marinelly was awarded the Siegbahn Prize for his incredible work on generating attosecond pulses at X-ray Free Electron Lasers. Finally, Melanie During—winner of this year's Photon Science Award for the best thesis of 2025—shared her research on how a multi-method approach, including X-ray tomography, helped pinpoint the season when dinosaurs went extinct.
A huge thanks to all our speakers for making the event memorable!
