1. Inference of Hierarchical Structure in Complex Systems
Abstract : Hierarchical organization is a central property of complex systems. It is even argued that a system is required to be hierarchical in order to evolve complexity within reasonable time. A hierarchy of a system is defined as the set of self-contained levels at which the system operates and can be described on. READ MORE

2. Development of rotation electron diffraction as a fully automated and accurate method for structure determination
Abstract : Over the past decade, electron diffraction methods have aroused more and more interest for micro-crystal structure determination. Compared to traditional X-ray diffraction, electron diffraction breaks the size limitation of the crystals studied, but at the same time it also suffers from much stronger dynamical effects.

3. Multimodal Imaging of Anisotropic Hierarchical Materials
Abstract : The thesis is focused on studying the nanostructure of natural and synthetic hierarchical materials with biological applications, using X-ray scattering imaging and birefringence microscopy. The term "hierarchical materials" is used for structures composed of sub-units organised in different length scales that create the building blocks for the next level. READ MORE

4. Dissipative formation of galaxies in hierarchical cosmology
Abstract : A description and detailed tests of a numerical code for simulations of galaxy formation is presented. The dynamics is followed with fully adaptive and Lagrangian Smooth Particle Hydrodynamics (SPH) combined with a gravitational tree method. The severe numerical problem of sub-resolution clustering is solved by merging of gas particles. READ MORE

5. Study of the flow-induced structure and anisotropy in lyotropic liquid crystals for hierarchical composites
Abstract : Controlling the micro and nanostructure of materials is highly beneficial in order to tailor their physical properties. Extrusion-based 3D printing is a promising tool to produce hierarchical structures with controlled architecture. READ MORE
