The confinement of molecular catalysts in metal-organic frameworks has the potential to lead to significant improvements in selectivity, long term activity and catalyst stability.

Can drugs that target host signaling pathways be used to eradicate antibiotic-resistant bacteria?

How is generative AI changing the way we learn, communicate, and make sense of the world today? As AI tools become part of everyday life, they don’t just produce text but shape meaning, influence trust, and impact how we find and share information. This project explores how people use, experience and…

This project investigates diversifying and democratizing heritage through practices of “home-making”. We propose to research ‘home-making’ as a non-binary practice of combining memories of roots and routes, dwelling in the present, and desires for the future.

LEGITIMULT examines how Covid-19 measures by governments impact multilevel governance and democratic governance in 31 European countries

To answer questions that look beyond individual entities, network science studies the interactions taking place in complex systems. These complex systems can often have temporal information on when an interaction occurs.

The Netherlands has a long history of mosquito-borne diseases, particularly malaria, until 1970 when it was declared malaria-free.

In this thesis, we investigate how deep generative models (AI models that can create new designs) can be better utilized for technical and industrial design. Our goal is to generate designs that are not only realistic (plausible), but also efficient, reliable, and usable in complex 2D and 3D applica…
