March, 2023- Fox on the media

Our pilot project about GPS tracking in urban carnivores has been featured in a local newspaper. Link.

September, 2022- Bat fieldwork

We have started the fieldwork from our project entitled: Bats in urban environments: what is the price of living in the city? funded by University of Zaragpza.

About me

I am a wildlife veterinarian broadly interested in the epidemiology of parasitic and infectious diseases in micro and mesomammals (carnivores, rodents, bats). For the past few years, I focus on vector-borne pathogens. I am also interested in animal conservation, diseases shared by wild and domestic animals, wild and peridomestic disease reservoirs, and zoonoses.

I am affiliated to the Instituto Agroalimentario de Aragón-IA2, based at the Veterinary Faculty of Zaragoza University. I am funded by the Aragonese Agency for R+D (ARAID). I am also a member of the research group "Zoonoses and emerging diseases of public health interest" (Official group #A16_20R of the Aragón Government).

I am a Cuncil Member of the Wildlife Disease Association and a Board Member of the Journal of Wildlife Diseases.

Current students

Grad students

I do not have any grad students at the moment. If you are interested in pursuing a Doctorate or Master's degree, contact me.

Undergrad students

I am currently supervising Veterinary Medicine Final Projects and the practices of several fourth-year students of Veterinary Medicine and Biotechnology degrees.

If you are interested in doing practices with wildlife, contact me.


I have supervised so far four PhD theses, three MSc/MRes theses and a number of grad projects.


I have a wide network of collaborators. Behind are some of these, with whom I am currently working.
