How are new drugs developed? This question is central to the Minor Modern Drug Discovery (MDD), which covers the entire trajectory from disease to drug molecule and vice versa. The various research groups involved offer a complementary and interdisciplinary perspective by connecting the diverse subjects…

In this thesis we construct an extension associated with the Furstenberg compactification of symmetric space of noncompact type. From this extension we get a cycle in equivariant KK-theory representing the extension. The construction of the extension and the corresponding cycle is a generalization of…

Urbanization brings benefits like housing and jobs but also challenges like biodiversity loss. CML's Urban research program uses science to create sustainable cities, focusing on the built environment (circular economy, urban mining) and enhancing urban nature for biodiversity and human benefits.

For present purposes, it is important to distinguish between an early period of settlement, about 6800-6200 BC, and a late period, about 6200-5800 BC, at Tell Sabi Abyad.

The majority of scientists, from archaeologists through to zoologists, collect enormous volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics and computer science, we can develop algorithms for analyzing…
