• Summary

    My research interests are in the area of ecology and biodiversity conservation, mainly focused on the Mediterranean endemic and threatened flora. During the past years, I have been studying reproductive processes of plant species, as well as their relationships with other species and the environment. In this sense, I have expertise in field and laboratory works, and also in using GIS and Species Distribution Modelling tools. Lately, my work is focused on ecological modelling and (spatial) data analysis.
