The coronavirus has the world in its grip. Finding a cure has never been more important. Unfortunately, the development of new drugs for treatment of the COVID-19 disease caused by the virus and development of a vaccine are complex, lengthy, and above all costly processes. With the help of computer…

Stars orbit black holes while jumping up and down. This is the prediction of a theoretical model developed by Leiden physicist Satish Kumar Saravanan, based on Einstein’s theory of relativity. He defends his PhD thesis on July 7th.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

This thesis is based on five papers on several topics.

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

The development process of any software has become extremely important not just in the IT industry, but in almost every business or domain of research.

Aim: To develop and enable application of a practical, flexible, user-friendly platform to provide the scientific community with a tool to generate land surface products and its associated uncertainties and exploit these for data-intensive science.

By making smart use of available data, the health and care of people can be substantially improved. Marco Spruit wants to use language and machine learning in the coming years to identify and solve the biggest care issues in the region of The Hague. He has been appointed Professor of Advanced Data Science…

He will join the CML-department of Industrial Ecology. He has a position at the Department of Applied Mathematics at the Faculty…

Which traits and/or trade-offs determine benefits of being deciduous or evergreen?

The 2019 Model ICAO took place from 21-24 May at the ICAO headquarters in Montreal.

Where did species survive the cold cycles of the current Ice Age?

Can birds - like people- ‘see’ voices and learn how to sing by listening and watching?

Mathematical biologists from Leiden have developed a model that helps to explain how the spine and vertebrae, among other things, form during embryonic development. The same process, the other way around, plays a key role in cancer metastasis. Publication in iScience.

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

The research programme Statistical Science is concerned with the analysis and interpretation of masses of data, the quantification of uncertainty using probability models, and the development and benchmarking of algorithms and methods with these aims.

This thesis describes the importance of being able to control the selectivity of potential drug candidates.

By training with virtual opponents known as computer generated forces (CGFs), trainee fighter pilots can build the experience necessary for air combat operations, at a fraction of the cost of training with real aircraft.

Since 2012, thousands of individuals have traveled from Western countries to join jihadist groups in Syria and Iraq. While much has been written about these individuals, only sparse attention has been paid to the social environment of these jihadist travelers and, more specific, the role of family members…

This paper written by Vydra and Kantorowicz answers the research question ‘What policy-relevant information does Twitter contain?’ as well as the research question ‘How does this information change between a period of normalcy and a period of crisis?’

What are the developmental pathways to social anxiety (disorder), the causal processes and maintaining factors? How do these factors interact in the development of social anxiety disorder? How can this knowledge be used to design and implement effective preventive intervention programs for youth?

Inactivating mutations in BRCA1 or BRCA2 genes predispose to several types of cancer.

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?
