De onderzoeksgroep Cyber Security Governance bestudeert de impact van moderne technologie op governance, soevereiniteit, wetshandhaving en internationale betrekkingen, en levert toonaangevend academisch onderzoek en beleidsinzichten.

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

To improve cancer treatments, personalized medicine approaches have aimed to identify exactly which mutations are driving tumor development in a given patient and specifically target these mutations using precision therapies.
