Every year, the Leiden Institute of Physics (LION) organises the Science Day. The goal is to highlight the newest research at LION, to socialise, and to welcome first year master students and new PhD candidates to our institute.

The next edition of the LION Science Day takes place on Tuesday 9 September 2025. We will organise an in-person event at the Hortus Botanicus in Leiden. There will be talks about research, and ample time to wander amongst exotic plants and discuss the challenges and joy of doing physics. Coffee, tea and lunch will be provided. The day will end with drinks for PhD and Master students.

All members of the LION community are also welcome. We will have special ‘advice sessions’ for Master students and first year PhD’s. More news about registration and program will follow shortly.
