1. Evolutionary Dynamics of Mutation and Gene Transfer in Bacteria
Abstract : The study of bacterial evolution is fundamental for addressing current problems of antibiotic resistance and emerging infectious diseases and lays a solid foundation for successful and rational design in biotechnology and synthetic biology. The main aim of this thesis is to test evolutionary hypotheses, largely based on theoretical considerations and sequence analysis, by designing scenarios in a laboratory setting to obtain experimental data.

2. 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.

3. 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

4. Comparative Genomics of Endosymbiotic Bacteria
Abstract : Genomes of intracellular bacteria are thought to be the products of reductive evolution. They have evolved from ancestral genomes of free-living bacteria through a process of massive gene loss. READ MORE

5. 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
