We are committed to provide you a meaningful, rigorous and quality graduate experiences in a personalized environment with a cutting edge research infrastructure and internationally renowned supervisors.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

Een minuscuul cirkelvormig stukje DNA zorgt ervoor dat de darmbacterie Clostridioides difficile resistent raakt tegen een veelgebruikt antibioticum. Dat ontdekten wetenschappers van het Leids Universitair Medisch Centrum (LUMC) nadat artsen hen attendeerden op een patiënt met een moeilijk behandelbare…

Can zebrafish provide a fast, sensitive in vivo vertebrate model for identifying novel mechanisms of Ewing sarcoma progression and for development of new anticancer compounds in a time- and cost-effective manner?

How to identify patients at risk of developing devastating, metastatic disease and facilitate the development of personalised treatment for prostate cancer patients?

A European consortium has provided a disruptive technological breakthrough to allow the discovery and characterization of novel enzymes for industrial biotechnology. The technology will open the way to more efficient industrial processes such as in the biofuel, animal feed and paper and pulp industr…

Asexual procreation in female wasps leads to an accumulation of genetic mutations, and the shrivelling of their sex organ. Leiden biologist Ken Kraaijeveld published this discovery in Evolution. His research is one of the first experimental studies into the consequences of asexual procreation.

Researchers at Leiden University have made a breakthrough in the study of the hereditary Pompe disease. Together with colleagues in York, they have developed a molecule that binds to the enzyme that is key to the progress of the disease. The findings have been published in ACS Central Science.

China’s booming aquaculture industry is increasingly dependent on fishmeal made from wild-caught fish, a practice that depletes wild fish stocks. A new study conducted by institutions including Leiden University and Stanford offers a more sustainable path. The study appeared in the journal Science on…

Tumours act like mini-organs, manipulating their environment and using bodily processes to survive and metastasise. Through research by Erik Danen and his colleagues, we are learning more about the complex nature of tumour cells. In the Dutch newspaper NRC, the scientists discuss their findings.
