We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

This thesis describes a study from both a theoreticaL and an experimental point of view.

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

Scientists at Leiden University (Netherlands), Stuttgart University (Germany) and Ural Federal University (Russia) have successfully put forward a novel, computed, reaction mechanism that was experimentally tested and show that formaldehyde is formed at much earlier stages in the birthplaces of stars…

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

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.

Microbial Sciences' contribution to the Host-Microbe Interactions research theme is to investigate how beneficial or disease-causing microbes associate and interact with their host.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

The SNP genotyping line offers flexible genotyping for small and large projects at affordable price and high quality. The use as SNPs as molecular markers is very versatile and can be used for a wide variety of scientific questions ranging from paternity analysis, conservatuion genetis towards QTL…

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

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.

The Biology programme offers 4 research-oriented specialisations corresponding with the research themes within the three institutes involved. You can choose a more practical-oriented specialisation if you would like to combine Biology with education, management business, or science communication.

Microbial Sciences' contribution to the Bioactive Molecules research theme is to discover new bioactive molecules and enzymes and unravel their mechanisms of action, regulatory networks, and the (bio)synthetic pathways required for their production.

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;
