1. On flexible random field models for spatial statistics: Spatial mixture models and deformed SPDE models
Abstract : Spatial random fields are one of the key concepts in statistical analysis of spatial data. The random field explains the spatial dependency and serves the purpose of regularizing interpolation of measured values or to act as an explanatory model. READ MORE

2. Spatial Mixture Models with Applications in Medical Imaging and Spatial Point Processes
Abstract : Finite mixture models have proven to be a great tool for both modeling non-standard probability distributions and for classification problems (using the latent variable interpretation). In this thesis we are building spatial models by incorporating spatially dependent categorical latent random fields in a hierarchical manner similar to that of finite mixture models. READ MORE

3. Statistical methods in medical image estimation and sparse signal recovery
Abstract : This thesis presents work on methods for the estimation of computed tomography (CT) images from magnetic resonance (MR) images for a number of diagnostic and therapeutic workflows. The study also demonstrates sparse signal recovery method, which is an intermediate method for magnetic resonance image reconstruction. READ MORE

4. Powder mechanics and dispersion properties of adhesive mixtures for dry powder inhalers : Conceptualized as a blend state model
Abstract : Inhaled medicines is a therapy that dates back several thousands of years. Nowadays, using various types of inhaler devices to deliver active pharmaceutical ingredients (APIs) to treat respiratory diseases has become common practice. READ MORE

5. Deconvolution of Spatial Gene Expression in Cancer
Abstract : Cancer is the second leading cause of death in the world, claiming nearly 10 million lives in 2020 alone. One of the main issues in anti-cancer treatment is the heterogeneity of the tumor microenvironment (TME). The TME consists of different cells that are critical for cancer development. READ MORE
