1. Probabilistic Models for Species Tree Inference and Orthology Analysis
Abstract : A phylogenetic tree is used to model gene evolution and species evolution using molecular sequence data. For artifactual and biological reasons, a gene tree may differ from a species tree, a phenomenon known as gene tree-species tree incongruence. Assuming the presence of one or more evolutionary events, e.g. READ MORE

2. Probabilistic Reconciliation Analysis for Genes and Pseudogenes
Abstract : Phylogeneticists have studied the evolution of life from single celled organisms to the astonishing biodiversity around us for a long time now. The relationship between species is often expressed as a binary tree - the tree of life. READ MORE

3. Culture-independent methods and high-throughput sequencing applied to evolutionary microbial genomics
Abstract : Culture-independent methods allow us to better understand the diversity of microorganisms on earth. By omitting the culturing step, we can gain access to species previously out of our reach.To better capture and understand the diversity of microorganisms, we have developed an alternative to 16S amplicon sequencing.

4. Genomic and evolutionary exploration of Asgard archaea
Abstract : Current evolutionary theories postulate that eukaryotes emerged from the symbiosis of an archaeal host with, at least, one bacterial symbiont. However, our limited grasp of microbial diversity hampers insights into the features of the prokaryotic ancestors of eukaryotes. READ MORE

5. Exploration of microbial diversity and evolution through cultivation independent phylogenomics
Abstract : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. READ MORE
