21. Celestial Orientation in Dim Light
Sammanfattning : The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. LÄS MER
22. Visually guided swimming in box jellyfish: A study of swimming behaviour in response to visual stimuli
Sammanfattning : Most animals use eyes to guide their behaviour. Analysing, and understanding, visually guided behaviours gets more complicated the more advanced the animal gets. Box jellyfish provide a relatively simple system for understanding visually guided behaviours. LÄS MER
23. Statistical methods in single particle fluorescence microscopy
Sammanfattning : The aim of this thesis is stochastic modeling and statistical inference in single particle fluorescence microscopy related to the experimental observation of randomly moving particles. A central theme is the use of single particle microscopy for estimation of absolute concentration of nanoparticles performing Brownian motion. LÄS MER
24. Digital holography and image processing methods for applications in biophysics
Sammanfattning : Understanding dynamic mechanisms, morphology and behavior of bacteria are important to develop new therapeutics to cure diseases. For example, bacterial adhesion mechanisms are prerequisites for initiation of infections and for several bacterial strains this adhesion process is mediated by adhesive surface organelles, also known as fimbriae.

25. Fish Lenses : Anatomy and Optics
Sammanfattning : I have investigated some of the biological regulatory mechanisms governing the development of crystalline lenses. I used fish as model animals because they possess optically interesting lenses, while the geometrical simplicity of fish lenses allows for studies that are difficult or impossible with the lenses of other animals.
