Postdoctoral Fellowships

Marie Skłodowska-Curie Actions (MSCA) aim to support the career development and training of researchers in all scientific disciplines through international and intersectoral mobility.

The fellows carry out their own research project in collaboration with a host institution, which is indicated at the time of their application. Researchers of all ages, nationalities and scientific disciplines can apply.

Postdoctoral Fellowships (MSCA-PF) provide an extremely enriching experience, that enhance the career perspectives for researchers by developing new scientific competences and gaining international and collaborative research experience.

Complutense as a Host Institution


The Complutense University of Madrid (UCM) is a public research university located in Madrid, and one of the oldest universities in the world (founded in 1499).

The UCM enrols over 80,000 students, almost 6,000 faculties and more than 3,000 administration and service staff and consistently ranks as one of the top universities in Spain. 

Research Groups

There are more than 200 UCM research groups interested in hosting researchers through MSCA Postdoctoral Fellowships.

They are looking for ambitious, creative and scientifically curious researchers who meet the MSCA-PF eligibility criteria.

If you are ready to take the next step in your research career look into our university's host offers.

European Office

The Complutense University of Madrid as host institution, through a dedicated European Research Office, supports MSCA Postdoctoral Fellowship candidates both in the application process and in managing the grant.

We offer, among other specific support services, an in-depth review of the proposal by experienced advisors: internal deadline to send the draft proposal to office is August 31, 2021.

Expressions of Interest

The next section include information about several UCM supervisors that have expressed their interests to host MSCA experienced researchers in their research group. If you are interested in one of them, you should contact the corresponding Scientific Supervisor directly.

The web search application will help you find the offer that best suits your interests. Just enable and use the filters (click on the filter icon). You can search by faculty, research area, and research topic to be proposed / description of the research group (by means of keywords). Visit the links provided in the search results (table below) to display further information.

Some offers the supervisors ask for particular documents. If you are required to submit a project proposal or you do not know exactly what send to present your candidature, you can use our template 'One Page Proposal'.

Group description
We are broadly interested in evolutionary biology, biogeography, behavioural ecology and conservation biology. Our study models are mostly birds, although lately we have been much focused on the bugs and microbes that live in their blood or on the plumage, in particular malaria parasites and feather mites. Our recent interests have included the following:

The tempo and mode of evolution of phenotypic diversity: we have analysed the historical diversification of avian migratory behaviours, how this process has driven phenotypic divergence of birds, and how the latter has affected bird interactions with parasites and other symbiotic organisms.

The ecology and evolution of host-symbiont interactions: we have studied birds and their symbionts (parasites, mutualists or commensals), paying special attention to the biogeography of interactions (from within-host symbiont coexistence to global symbiont diversity) and the evolution of different host exploitation strategies among symbiont species.

The implications of life history variation in disturbed habitats: we have been looking at the impact of recreational activities on wild bird populations, aiming to produce knowledge that may help to reconcile nature recreation and wildlife conservation.

Javier Pérez-Tris leads the Evolution and Conservation Biology group at UCM, which has been evaluated as EXCELLENT by the Spanish Research Agency (February 2018).

Research topic
Ecological networks, the sets of links that connect species to one another through their ecological functions, constitute the foundation of biodiversity, and the understanding of their properties and dynamics represents one of the most important challenges for our society, faced with the global change of ecosystems. Most studies of ecological networks use species as basic interactors, assuming that all individuals of a species have the same ecological role. However, there is intraspecific variability in individual traits or properties related to the establishment of interactions among species. In mutualistic networks connecting plants with their pollinators and seed dispersers, an individual's preference to feed on --and therefore disperse pollen or seeds of-- one or another plant species may depend on individual nutritional needs, which in turn depend on the health status of the individual. We are exploring these types of extrinsic influences on network properties using two study systems: the network that links hummingbirds with the plants they pollinate, and the one that links understory birds with the plants they help to disperse. We will analyze the effect of avian malaria and virus infections on the structure and properties of these networks. We hypothesize that diseased birds will prefer distinctive sets of plant species, particularly those that contain nutrients important for their maintenance in the face of infection.If network properties change predictably depending on which individuals (infected or healthy) are used to calculate network parameters, the architecture of mutualistic networks will depend on pathogen prevalence, an overlooked mechanism to explain disease impacts on ecosystems with important implications for ecology and conservation biology.

Tenure-Track Position for Marie Skłodowska-Curie Global Fellowships?

The "Plan de Actuaciones en Profesorado 2020-23 (ES)" of the Complutense University includes among its calls several options for further hiring of researchers with a PhD. All options require an excellent CV and being granted National Accreditation.

Among the requirements for the stabilization of a Researcher to Assistant Professor, it is required that the researcher has spent at least 3 years as a researcher hired by the UCM in a competitive public call.

Global Fellowships are open to researchers currently within or outside Europe who want to move to a Third Country for 1-2 years and then come back to the Complutense University for an additional year. Therefore, researchers who have been awarded a three-year Global Fellowship would be, after the end of the project and with the current regulatory framework, in a position to meet this condition.

In certain situations, it has been possible for a researcher with at least 2 years working at UCM to opt for a position as a junior Associate Professor.
