16. Evolutionary Ecology of Floral Traits in Fragrant Orchids
Abstract : Why are flowers so diverse? Much of floral evolution is thought to be driven by pollinator-mediated selection. However, the connection between macroevolutionary patterns of floral diversity and microevolutionary processes remains poorly understood. In this thesis, I have used the fragrant orchids Gymnadenia conopsea s.s. READ MORE

17. The roles of demography and natural selection in shaping genome-wide variation of Norway spruce
Abstract : Understanding the relative contribution of genetic drift, natural selection, and mutation to genetic variation, and quantifying adaptive evolution and the effects of natural selection in species are enduring goals of evolutionary genetics. Norway spruce (Picea abies) is one of the most important conifer species that dominates from both an ecological and economical point of view in many boreal ecosystems. READ MORE

18. Evolutionary consequences of sex-specific selection
Abstract : Sex-specific selection is widespread, evident by the evolution of sexual dimorphism in many traits in sexually reproducing taxa. The reason why the sexes may experience selection that differs in direction or magnitude is often linked to the reproductive strategies associated with the sex-specific reproductive physiology.

19. Statistical Feature Selection : With Applications in Life Science
Abstract : The sequencing of the human genome has changed life science research in many ways. Novel measurement technologies such as microarray expression analysis, genome-wide SNP typing and mass spectrometry are now producing experimental data of extremely high dimensions. READ MORE

20. Island biogeography and population divergence in the Skyros wall lizard
Abstract : Islands are cradles for new biodiversity and provide natural laboratories for the study of population divergence. In my thesis, I investigated the role of different evolutionary processes in the population divergence in the Skyros wall lizard (Podarcis gaigeae), a species where islet populations have strongly diverged morphologies.
