1. Genetic epidemiology of cardiometabolic biomarkers : twin studies in the genomic era
Abstract : Following the Human Genome Project, many genomic approaches have been developed in genetic epidemiology to investigate the genetic influences on human complex traits. This thesis aims to answer four genetic epidemiological questions for cardiometabolic biomarkers/ traits, by using classical twin studies and novel genomic methods. READ MORE

2. Characterization and Optimization of Silicon-strip Detectors for Mammography and Computed Tomography
Abstract : The goal in medical x-ray imaging is to obtain the image quality requiredfor a given detection task, while ensuring that the patient dose is kept as lowas reasonably achievable. The two most common strategies for dose reductionare: optimizing incident x-ray beams and utilizing energy informationof transmitted beams with new detector techniques (spectral imaging). READ MORE

3. Spin Properties in InAs/GaAs Quantum Dot based Nanostructures
Abstract : Semiconductor quantum dots (QDs) are a promising building block of future spin-functional devices for applications in spintronics and quantum information processing. Essential to the realization of such devices is our ability to create a desired spin orientation of charge carriers (electrons and holes), typically via injection of spin polarized carriers from other parts of the QD structures.

5. Observational Uncertainties in Water-Resources Modelling in Central America : Methods for Uncertainty Estimation and Model Evaluation
Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE
