1. Birth and Death Processes in Random Environments
Abstract : This thesis treats birth and death processes in random environments. They are modelled by Markov processes in Z+2, where the first component represents the object of interest, the "birth and death process", and the second component represents the random environment which is assumed to be a time homogeneous Markov process in its own right.

2. Probabilistic Programming for Birth-Death Models of Evolution
Abstract : Phylogenetic birth-death models constitute a family of generative models of evolution. In these models an evolutionary process starts with a single species at a certain time in the past, and the speciations—splitting one species into two descendant species—and extinctions are modeled as events of non-homogenous Poisson processes.

3. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression
Abstract : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.

4. Two-Barrier Problems in Applied Probability: Algorithms and Analysis
Abstract : This thesis consists of five papers (A-E). In Paper A, we study transient properties of the queue length process in various queueing settings. We focus on computing the mean and the Laplace transform of the time required for the queue length starting at $x0. We define the loss rate due to the reflection. READ MORE

5. Early and later life mechanisms in the aetiology of cardiovascular disease
Abstract : Evidence over the recent decades indicates that susceptibility to cardiovascular disease (CVD) may be established already prenatally and in early childhood, and that the aetiological processes of the disease involve biological and social influences occurring throughout a person’s life span. Numerous studies have shown that small size at birth is associated with increased risk of CVD later in life. READ MORE
