Research Interests

I am a Nature fan since I was a child. I was fascinated (and still I am) in animals and their behaviors, why plants grow where they do or in communities of marine invertebrates in the rocky coast around my small town. This enthusiastic attitude resulted in a Bachelor and a PhD in biology. During my dissertation, I dived in a special host-parasite system: bacterial community on bird eggshells and their relationship with avian life history traits. I am still working in this really interesting research line extending their limits to other bacterial community as in the skin of vertebrates, in the geographical variation of bacterial communities and egg defenses or the role of egg coloration in bacterial assemblages. This research line have pushed me to develop an interdisciplinary formation, a good network of collaborators and have woke up new avenues for my research. I am also interested in other topics as migration patterns and behavior, bacterial community ecology or other host-parasite interactions.

In other words:

Bacteria-Vertebrate interactions
   - The role of bacterial community on life history traits and fitness of birds
   - Bacteria on the vertebrate skin
   - Geographical variation in gut microbiota in birds
   - Influence of diet in gut bacteria and vertebrate behavior

Migration patterns and behavior
   - Swallows in South Spain
   - Climate changes and migration timing
   - Route changes in white storks
