Inviting members of the public to help monitor wildlife, photograph plants or conduct samplings. These are some of the many examples of Citizen Science. It is increasingly recognized as effective and impactful for collecting data, but also for engaging the public in scientific research. In Nature reviews…

About one and a half million people worldwide die each year from tuberculosis. For thirty years, therapy with antibiotics has been the same, while it takes far too long and can lead to resistant pathogens. Leiden researchers from four institutes are now joining forces to develop more effective and efficient…

Are you thinking of applying for a Kiem grant but still tinkering with your idea for an interdisciplinary project? Let your Leiden colleagues inspire you! Dario Fazzi successfully applied for a Kiem grant with his workshop ‘Understanding the threat of the Anthropocene’.

How do we prepare our students for a future labour market in which flexibility, resilience and adaptability are essential?

Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

How do digital technologies affect adolescent mental health and resilience? How do we foster a secure online environment? How should we deal with increasing rates of online crimes among adolescents? During the mini-symposium ‘The effect of the online world on adolescents’, presented by the interdisciplinary…

In a supplementary decision on 17 May 2022, the Executive Board of Leiden University has concluded that it will publish the titles of seven articles in which there is evidence of malpractice. This concerns a former staff member of the Institute of Psychology. The Executive Board considers it to be in…

On 12 January ten driven lecturers obtained their Senior Teaching Qualification (SKO). Rector Magnificus Hester Bijl congratulated them in the Academy Building. We asked three of them how the SKO programme had benefitted them, what they think ‘good teaching’ is and what makes them so passionate about…

Her plan was to obtain a PhD, but, during her master’s, alumnus Sangbreeta Moitra discovered that her true interest lay in applying neuroscience in everyday life.

No fewer than 55 applications were submitted for a Kiem seed grant, an initiative for developing new interdisciplinary, interfaculty research partnerships and encounters. The draw took place on Monday for the allocation of 22 seed grants. The Executive Board was so impressed with the number of applications…

Knowing whether or not a treatment is working just by wearing your watch? Data scientist Ahnjili ZhuParris has identified a lot of opportunities for the use of machine learning in clinical research to monitor test subjects at home.
