Lines of Research

1.     Great ape genetic variation in the context of  human evolution and conservation biology.


Characterizing the variation of thousand of human genomes is standard today. However, primates (our closest relatives) are the ideal set of species to study the evolution of these features from both mechanistic and adaptive points of view.

In this line of research, we use genomic approaches in primate genomes to understand the impact of variants in the evolution of every species to provide a proper perspective to the differences among species.

2. Comparative gene regulation in humans and primates


DNA methylation is an epigenetic modification involved in regulatory processes such as cell differentiation during development, X-chromosome inactivation, genomic imprinting and susceptibility to complex disease. However, the dynamics of DNA methylation changes between human and their closest relatives is still poorly understood. In this project, we evaluate methylation patterns in recent human evolution. We identified a significant positive relationship between the rate of coding variation and alterations of methylation at the promoter level.

 3. Canid evolution.


        The domestic dog has been widely recognized as an important organism for studying the relationship between selection, genome variation, and phenotypic diversity. Both dogs and wolves have been extensively surveyed using mtDNA, microsatellites, SNPs  but structural variation, including variation in multicopy gene families, has not been fully characterized in canines.
