Chemotherapy, but without hair loss or extreme fatigue. It may be possible if the toxic drug only becomes active where it is ‘switched on’ by light. Matthijs Hakkennes has helped bring that idea closer to reality and obtained his PhD cum laude. ‘I received many thank-you emails from China and Bangla…

Preventing viral infections from being transmitted through blood transfusion and organ transplantation lies at the heart of the work of medical microbiologist and virologist Mariet Feltkamp and her team.

One in two people will be diagnosed with cancer. World Cancer Day on 4 February raises awareness of the impact of this devastating disease. Leiden University is conducting various studies aimed at preventing and controlling cancer. Below are just a few examples.

Leiden PhD student Xuequan Zhou has designed a new promising molecule that efficiently kills cancer cells, but does not harm healthy tissue. The trick: the drug is only active when irradiated with light. Zhou’s new compound does this extra efficiently by cleverly self-organising into nanoparticles.…

My name is Eliza Steinbock, I’m 38 years old and I was born and raised in Louisville, Kentucky in the United States. I started teaching and researching at Leiden University in 2014. I research and teach gender representation, mostly of transgender people, in media and culture.

Apps to help people stop smoking, eat more healthily or exercise more are everywhere. eHealth programmes are abundant, yet they are often not accessible to people with lower incomes and levels of education. For her PhD research, Isra Al-Dhahir investigated how this could be improved.

How does online learning strengthen the quality of higher education and what are the barriers to implementing this more broadly? Minister of Education Ingrid van Engelshoven talked about this issue with pioneering lecturers and students from Leiden University, Erasmus University and Delft University…

Xander Tielens, Professor of Physics and Chemistry of the Interstellar Space, has been awarded an ERC Advanced Grant to study polycyclic aromatic hydrocarbons (PAHs) in space. The combination of astronomical observations, computer models and lab research makes the research highly interdisciplinary.

In March 2022, a considerable number of non-Western countries abstained (35) or voted against (5) a resolution deploring Russia’s aggression, its violation of the UN Charter and demanding the withdrawal of its forces from the territory of Ukraine. Even fewer countries subsequently actively supported…

NWO has awarded eleven Leiden researchers a Vidi grant of 800,000 euros. The research subjects range from Cicero and muscle dystrophy to the archaeology of bogs.

Imagine scanning lion dung or a mouse dropping and instantly knowing exactly what and how much the animal has eaten. Thanks to new DNA techniques, this is becoming increasingly feasible. PhD student Kevin Groen tested how effective these techniques are at unraveling the diets of wild animals.

The impact of a ceasefire shifts over the course of a conflict, as conflict party leaders learn more about each other’s military and political aspirations and adapt their use of ceasefires accordingly. That’s the key message of the dissertation of Valerie Sticher, PhD-candidate at the Faculty of Governance…

Having mostly ignored the gains Dutch traders, investors and firms attained from serving the French, English and Iberian empires, debate in the Netherlands now demands a re-evaluation of Dutch colonial responsibilities.
