1. Nucleotide Substitution Patterns in Vertebrate Genomes
Abstract : The rates and patterns at which nucleotide substitutions occur vary significantly across the genome sequence of vertebrates. A prominent example is the difference in the rate of evolution of functional sequences versus nonfunctional (neutrally evolving) sequences, which is explained by the influence of natural selection on functional sequences.

2. Characterization of non-coding mRNA in Epstein-Barr virus
Abstract : Epstein-Barr virus (EBV) is a human gammaherpesvirus that infects lymphoid and epithelial cells. The virus is the causative agent of infectious mononucleosis, a self-limiting lymphoproliferative disease, and it is additionally associated with various malignancies including Burkitt?s lymphoma, Hodgkin?s disease and lymphoproliferative syndromes in immunocompromised individuals.

3. Comparative Genomics in Birds
Abstract : To shed light on forces that shape the molecular evolution of bird genomes, and in turn avian adaptations, comparative analyses of avian DNA sequences are important. Moreover, contrasting findings in birds to those of other organisms will lend a clearer view on general aspects of molecular evolution. READ MORE

4. MHC and genomic diversity in Atlantic salmon (Salmo salar L.)
Abstract : In this thesis I present studies concerning genomic diversity and genetic heterogeneity as well as the evolution and maintenance of genetic variation at a specific immune defence gene in Atlantic salmon (Salmo salar, L.). READ MORE

5. Birds as a Model for Comparative Genomic Studies
Abstract : Comparative genomics provides a tool to investigate large biological datasets, i.e. genomic datasets. In my thesis I focused on inferring patterns of selection in coding and non-coding regions of avian genomes. READ MORE
