General Interests: Application of molecular and computational tools within a phylogenetic framework to interpret organismal diversity (in fish particularly) and to understand their mechanisms of evolution. Currently, I am working on the Cypriniformes tree of life (CToL) project – a phylogenomic perspective.

During my doctorate study (at Laboratoire d’Ichtyologie générale et appliquée and Service commun de systématique moléculaire, Muséum National d’Histoire Naturelle à Paris under the supervision of Dr. Guillaume Lecointre), my research was focused on a systematics project of acanthomorph fishes, the most diverse group of vertebrates. My work was the first attempt to summarize multi-locus data for an extensive taxonomic sampling of acanthomorphs. I also worked on small-scale phylogeny of higher notothenioids (Antarctic acanthomorphs, composed of the families Harpagiferidae, Artedidraconidae, Bathydraconidae, and Channichthyidae) based on two mitochondrial genes. The comparison with phylogeography and ecology of included channichthyid taxa allowed proposing putative speciation models and correlations with paleo- events of Antarctic Ocean.

 I embarked on my first postdoctoral training at the University of Nebraska-Lincoln (with Dr. Guillermo Orti) and then went to France for a postdoctoral work with Dr. Guillaume Lecointre before coming to Saint Louis University to work with the Cypriniformes Tree of Life initiative.
