I am a Research Leader within the Character Evolution team. My main scientific interest is to understand the evolutionary mechanisms governing plant genome size diversification and its significance in a changing environment.
My research takes advantage of the extensive gardens collections and overseas field expeditions, and integrates both laboratory work and applied bioinformatics in the following areas:
- Model-based analyses to study genome size and chromosome evolution (including physical DNA organisation) across several land plant groups.
- Genomic approaches to comprehensively explore plant giant genomes using next generation sequencing technologies.
- Large-scale genome dynamics in the course of plant radiations, with a particular focus on island colonisations.
- BSc, University of Valencia, 2004
- MSc, University of Barcelona, 2006
- PhD, University of Barcelona, 2009
- University of Barcelona PhD prize for the best thesis in Plant Sciences 2009-10
