1. 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

2. Phylogenomics of Oceanic Bacteria
Abstract : The focus of this thesis has been the phylogenomics and evolution of the Alphaproteobacteria. This is a very diverse group which encompasses bacteria from intraceullar parasites, such as the Rickettsiales, to freeliving bacteria such as the most abundant bacteria on earth, the SAR11.

3. Phylogenomic Analysis of Vertebrate Evolution
Abstract : The field of phylogenomics has emerged during the last five years, as the number of fully or partially sequenced genomes has increased rapidly. Using whole genomes for phylogenetic studies greatly increases the accuracy of the trees determined, and can potentially resolve phylogenetic questions that could not be resolved bu studies using only a few gene sequences.

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. Symbiosis in Arbuscular Mycorrhizal Fungi : Unearthing genomic signatures
Abstract : Arbuscular mycorrhizal (AM) fungi have been on earth since 470 million years ago. AM fungi form mutualistic symbiosis with most terrestrial plants and thus, are thought to have played important roles in land colonization together with plants. READ MORE
