ABOUT ME

I am a behavioural ecologist and Postdoctoral Research Associate in the Rubenstein Lab in the Department of Ecology, Evolution and Environmental Biology at Columbia University. My research interests focus on answering ultimate questions on the evolution of animal behaviour, with particular interest on social evolution and cooperation. For that, I take an integrative approach that includes theoretical models, experimental and observational empirical research, and comparative methods to generate and test novel hypotheses.

During my postdoc at Columbia University with Prof. Dustin Rubenstein, I investigate the evolution of cooperation by exploring the phenomenon of age-dependent task specialization in vertebrates. In addition, I look at the role of reproductive conflict mediating sociality in different ecological environments. I use a combination of theoretical models and comparative methods, as well as field based empirical research using the superb starling as model species.

I obtained my PhD in Ecology and Evolution at the University of Bern with Prof. Michael Taborsky. I investigated different direct and indirect fitness benefits that shape the evolution of cooperative breeding, in particular the pay-to-stay and group augmentation hypothesis in connection with kin selection. I used a combination of mathematical and computational modelling, with behavioural experiments in the model species Neolamprologus pulcher, a cichlid fish from Lake Tanganyika.

I did my maters in Animal Behaviour at the University of Exeter. During my master’s thesis with Prof. Tim Fawcett, I investigated how males may adjust courtship displays depending on the number of rival signalers, and how flexible displays may coevolve with the female preference using a theoretical approach.

I received my Bachelor degree in Biology at the University of Valencia. During my bachelor’s thesis with Prof. Juan S. Monrós, I researched the phenology of emergence of different species of cave dwelling bats during their breeding period. I focused on how the raise in their energetic expense at different reproductive stages is traded against a higher predation risk of earlier emergence.
