11. Evolution of the Neuropeptide Y System in Vertebrates with Focus on Fishes
Abstract : Gene families in vertebrates often contain more dulicates (paralogs) than in invertebrates. This has been attributed to genome duplications, i.e., tetraploidizations. READ MORE

12. Evolution of acetylcholine receptors and study of the anatomy of the mouse brain reward system
Abstract : This thesis work is divided in two parts. In the first part, I make use of the transgenic TRPV1-Cre mouse line as a tool to investigate the midbrain ventral tegmental area (VTA). READ MORE

13. Origin and the evolution of diatoms through the integration of paleontology and phylogenetics
Abstract : Diatoms, the prominent photosynthetic eucaryotes, have inhabited the world’s oceans for at least the past 120 Ma since their first appearance in the Lower Cretaceous. There are also records of older diatoms, from the Jurassic dating to ca. 172 Ma and ca. 165 Ma, however these are poorly documented. READ MORE

14. Sculpted through Time : Evolution and Function of Serine Proteases from the Mast Cell Chymase Locus
Abstract : Immune cells like NK cells, T cells, neutrophils and mast cells store high amounts of granule serine proteases, graspases. Graspases are encoded from the mast cell chymase locus. The human locus holds four genes: α-chymase, cathepsin G, and granzymes H and B. In contrast, the mouse locus contains at least 14 genes. READ MORE
