Our research group develops and improve methods of phylogenetic reconstruction based on mathematical tools, specially algebraic, semi-algebraic and geometrical tools. This includes studying molecular substitution models from a mathematical point of view in order to guarantee parameter identifiability and to provide model selection tools. Our research lies in the borders of phylogenetic reconstruction, algebraic statistics, algebraic geometry and computational algebra.

We are part of the larger research group GEOMAP: GEOMetry and APplications.
