We are a growing team at the Estación Biológica de Doñana (Spanish National Research Council, CSIC). We have broad interests within the ecology and evolution of birds and their symbionts (see Research). Each member develops his/her own research, with different topics and approaches. We also have the pleasure to collaborate with several international collaborators. Inquiries from prospective students and postdoctoral researchers are welcome.
