The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Antibiotic-resistant bacteria pose a major health threat. Addressing this challenge requires among others the development of new antibacterial compounds. The research described in this thesis focuses on discovering novel antibiotics from soil bacteria, specifically Streptomyces and Paenibacillus.Despite…

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

Streptomyces are prolific producers of enzymes and secondary metabolites, including more than 50% of all clinical antibiotics. This makes them highly attractive for medical, biotechnological, and industrial purposes.

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

The investigations described in this thesis lay out strategies aimed at advancing antibiotic research and development. The examples presented revolve around two main approaches: understanding drug-target interactions and target identification.

Optimization tasks in practice have multifaceted challenges as they are often black box, subject to multiple equality and inequality constraints and expensive to evaluate.

Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

This dissertation presents new cryptographic protocols, which can be divided into two families.

In this PhD-thesis several new and existing data science application are described that are particularly focused on applications for tax administrations.
