1. The accessibility paradox : Everyday geographies of proximity, distance and mobility
Abstract : This thesis aims to explore the importance of proximity and mobility, respectively, for individuals’ accessibility, as well as the relationship between these two key spatial dimensions of accessibility in the context of everyday life. The thesis is based upon three empirical research papers which focus on accessibility-related preferences, actual accessibility conditions, and travel patterns. READ MORE

2. Computational methods for analysis of spatial transcriptomics data : An exploration of the spatial gene expression landscape
Abstract : Transcriptomics techniques, whether in the form of bulk, single cell/nuclei, or spatial methods have fueled a substantial expansion of our knowledge about the biological systems within and around us. In addition, the rate of innovation has accelerated over the last decade, resulting in a multitude of technological advances and new methods for generation of transcriptomics data. READ MORE

3. Essays on Distance Based (Non-Euclidean) Tests for Spatial Clustering in Inhomogeneous Populations : Adjusting for the Inhomogeneity through the Distance Used
Abstract : This thesis consits of four papers dealing with distance based (non-Euclidean) tests for spatial clustering in inhomogeneous populations. The density adjusted distance (DAD), which considers the underlying density, is defined in the first paper. READ MORE

4. Spatial Spread of Organisms : Modeling ecological and epidemiological processes
Abstract : This thesis focuses on the spread of organisms in both ecological and epidemiological contexts. In most of the studies presented, displacement is modeled with a spatial kernel function, which is characterized by scale and shape. These are measured by the net squared displacement (or kernel variance) and kurtosis, respectively. READ MORE

5. Spatial analysis and modeling of urban transportation networks
Abstract : Transport systems in general, and urban transportation systems in particular, are the backbone of a country or a city, therefore play an intrinsic role in the socio-economic development. There have been numerous studies on real transportation systems from multiple fileds, including geography, urban planning, and engineering. READ MORE
