The Graduate School of Science offers PhD programmes spanning the entire spectrum of science from Mathematics to Environmental Science.

The Department of Biophysical Structural Chemistry studies how biological systems work at the molecular level through high-resolution structural analysis. Using state-of-the-art techniques in structural biology such as cryo-electron microscopy and X-ray crystallography we gain crucial insights into…

Many researchers of the Faculty of Science are members of a research school related to their area of expertise. Research schools aim at collaboration of researchers from different faculties in the same university (interfaculty schools) or in different universities (interuniversity schools).

In this thesis unconventional tools based on fluidic interfaces were developed to study the surface and interfacial chemistry of graphene, to characterize the intrinsic properties of graphene, to disentangle the effects of substrate and of the environmental factors, and to improve handling protocols…

In this thesis I highlight the applications of Oxford Nanopore Technologies (ONT) sequencing. This technique is a relatively new approach in the sequencing field, where nanopores are embedded in a membrane, DNA molecules are pulled through nanopores and an electrical current serving as the sequencing…
