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!
