Research at the Leiden Institute of Physics (LION) is foundational and curiosity driven. All our scientists share a desire to increase the knowledge of the world around us, in an open atmosphere of inquiry from which innovative ideas emerge that provide applications and value for society.

Persistent somatic symptoms are long term symptoms that lack a clear medical explanation. These symptoms have a high prevalence where most people know someone who experiences such symptoms or they experience such symptoms themselves. Symptoms can vary greatly in and between people. While one person…

Research groups in the Biological & Soft Matter Programme unravel mechanisms in biological processes and develop novel bio-inspired soft materials.

This master’s programme combines Physics with Data Science. You will learn how physics has its own tricks to deal with big data and how techniques from machine learning and deep learning can be applied to classical and quantum data. The first focus of attention is on classical data, including data mining,…

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

The Tatiana Afanassjewa-lecture series is a series of public talks in Dutch by Leiden physicists on wednesday evenings, intended for everyone with an interest in physics.

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.
