Actual occupation: PhD Student.
Institution: Universidad de Chile
Research on: Evolutionary patterns and historical biogeography in snails from the Altiplano.

Educational Background:

2014 – Present. PhD. in Ecology and Evolutionary Biology, Universidad de Chile. Dissertation title: “Phylogenetic relationships and historical biogeography in freshwater snails of the genus Heleobia Stimpson, 1865 (Caenogastropoda: Cochliopidae) from the Andean Altiplano”. Advisors: Marco Méndez and Gonzalo Collado.

2012 – 2015. MSc, Universidad de Chile. Dissertation title: “Genetic and morphological differentiation in Heleobia ascotanensis (Courty, 1907) (Caenogastropoda: Cochliopidae) from Ascotán salt pan, Chilean Altiplano”. Advisors: Marco Méndez and Gonzalo Collado.

2007 – 2011. BSc, Universidad de Chile.

Research Interest: My research interest focuses on phylogenetics, systematics, phylogeography and species delimitation of freshwater gastropods. I study what factors promote and constrain macroevolutionary and microevolutionary processes that govern the species diversification in freshwater organisms. I have also studied the impact of glacial periods on population structure of snails in fragmented habitats. Most of my research relies on combining genetic data with other phenotypic and biogeographic information to make inferences about evolutionary processes. Currently, my main focus is on evolutionary processes in the genus Heleobia, but I have been working on comparative phylogeography using amphibians, fishes and other snails from different hydrological systems in the Andean Altiplano.
