Main Research Interests

My main research interests are is on genetic evolutionary processes leading to the diversification of fish species. At present I am specifically interested in understanding the role of homoploid hybridization in the evolution of Iberian cyprinids, more specifically on inter-specific introgression patterns. I am also involved in research projects on the phylogeography and population structure of freshwater and marine fish.


Academic Qualifications

- 2005 PhD in Biology (University of Southampton)

- 1999 5-year college graduation in Biology Applied to Animal Resources (University of Lisbon)
