21. A forest dark : an evolutionary history of Norway spruce
Abstract : Embedded within the relationships among species is a dense forest of gene trees, each with a potentially unique and discordant history. Such widespread genealogical heterogeneity is expected, but embracing this hierarchy of discordance while reconstructing the histories of populations and species remains a major challenge. READ MORE

22. The Molecular Evolution of Snakes as revealed by Mitogenomic Data
Abstract : Snakes (Serpentes) are a diverse suborder of reptiles that, along with lizards and amphisbaenians, belong to the reptilian order Squamata. The phylogenetic position of snakes relative to lizards and amphisbaenians has been debated for about 140 years. READ MORE

23. The Genetics of Adaptation and Evolvability in Yeast
Abstract : Evolution is the hereditary change in life forms that has shaped the divergence of all organisms that inhabit planet Earth. I used the yeast Saccharomyces cerevisiae to study how adaptive evolution increases the fitness and changes the properties of experimental and natural yeast populations. READ MORE

24. In silico Studies of Early Eukaryotic Evolution
Abstract : A question of great interest in evolutionary biology is how and why the eukaryotic cell evolved. Several hypotheses have been proposed, ranging from an early emergence of a primitive eukaryotic cell, to various fusion models like the hydrogen hypothesis. Within this context, relevant bacterial gene families and genomes are examined in this thesis. READ MORE

25. Genomic strategies towards the dissection of human complex disease
Abstract : Complex diseases are caused by the activities of many genes acting in concert with environmental factors. A major challenge facing human genetic research is to unravel the genetic factors behind complex disorders. READ MORE
