I received a Ph.D. in Evolutionary Biology from the University of Lisbon in 2013 and I am currently working in the Evolutionary Genetics Group, in the Chromosomal Evolution Subgroup of cE3c. I have been occasionally a teaching assistant of Cytogenetics at the Faculty of Sciences – University of Lisbon. My research focuses on the causes and consequences of natural hybridization events in terms of genome rearrangements as seen from the karyotype point of view.
For many years I have been involved in the research of natural hybridization cases using Iberian cyprinids as model systems. Namely, the homoploid Chondrostoma s.l. system and the allopolyploid Squalius alburnoides species complex.
Our team has collaborations with national groups renowned for Cytogenetics and Evolution (UTAD/Vila Real; ISA/Lisbon), as well as with international groups expert in Fish Cytogenetics and Evolution (IAPG/Czech Republic; UEPG/Brazil), and Meiosis (Universidad Complutense de Madrid/Spain).
My current research is driven by three overarching main questions:
1. How far goes the apparent conservative karyotypes of Leuciscinae (Cyprinidae) in contrast to the high biodiversity levels in the Iberian Peninsula (what rearrangements underlie the species- and population-specific sub-chromosomal differentiation)?
2. How do foreign genomes interact in a hybrid environment (interaction and persistence of parental genomes in the different hybrid forms found in nature)?
3. What is the actual value of such hybrids for conservation purposes (adaptation, speciation)?
