The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

The first book ever on information-theoretically secure multiparty computation

The book offers different theoretical perspectives to help examine the process of public sector reform. In addition it gives an overview of the major trends in the core areas of the functioning of the public sector.

Morphology is the grammar of words. Morphologists study how words are built and what principles govern their form and their function.

Our group operates at the cross-roads of different disciplines: molecular and cellular microbiology, biochemistry, structural biology and biophysics. The group harbors expertise in a multitude of molecular and cellular approaches including:

This research profile area brings together descriptive, historical and theoretical linguistics, as well as psycho- and neurolinguistics.

A network combining 9 academic research groups and 4 collaborating industrial companies will train the next generation of PhD students and post-doctoral researchers, in developing and applying novel experimental and theoretical methods in the NMR spectroscopy of systems containing paramagnetic metals.…

How do technologies of computer vision, which promise to replace humans in the understanding of images, work in practice in the field of security, and what are their ethical and political implications?

The master's specialisation Clinical Neuropsychology consists of three main parts: the mandatory and elective courses, a thesis and an internship.

Not all problems are easy to solve, but with enough bright minds, you make progress step by step. ‘The kind of problems I am interested in have been occupying mathematicians for over two millennia,’ says theoretical mathematician David Lilienfeldt. In September, he started at the Mathematical Institute…

Does gravity work the same when you look at the largest scales in our universe? That’s what Leiden physicist Alessandra Silvestri will study with a 2 million euro ERC Consolidator grant. ‘We assume that it does, but we don’t actually know.’

Theoretical physicist Stephen Hawking (76) passed away on 14 March at his home in Cambridge, having been a long-term sufferer of the muscular disease ALS. A number of Leiden scientists look back at the life and scientific career of this world-famous physicist. 'He was very approachable and extremely…

There are over 7,000 languages in the world and over half of the world’s population is bilingual. But how do all these people use their language? And how do these languages differ from one another? Under the slogan of ‘Interconnecting linguistic diversity,’ the researchers from the Leiden University…
