I'm a quantitative marine ecologist interested the ecological and evolutionary consequences of fish life-history variation.

  • What are the causes and consequences of individual life-histories?
  • How individual life-histories affect sustainability and ecosystem dynamics?
  • How exploitation (fisheries) and environmental regime shifts imposed by Climatic Change or biological invasions shape fish life-histories?
  • How we can integrate the human dimension in the sustainable development of oceans?

These are my main research questions which I try to shed light by producing novel theory and scientific data using state-of-the-art methods (tracking technologies, artificial intelligence and high-throughput -omics), and using a trans-disciplinarily approach that integrates “communities of practice” with the final goal of preserve and sustainably use the oceans, seas and marine resources as promoted by the United Nations (SDG14).


Short biography - In 2007, as just a post-graduate, I was awarded my first project as PI. In 2011, I completed my MSc degree in Marine Ecology and I was awarded with a competitive national Fellowship to carry out my PhD (FPI). I successfully defended my PhD with Honours at the University of the Balearic Islands (UIB) in 2013, and when I was still a PhD student, I was awarded a two-years Marie Curie IEF Post-Doc Grant (IEF, ~15% success rate, 160k, European funding, 24 month) to develop my first post-doctoral stage (2014-2015) in a world-leading group on social-ecological systems (IGB, Germany). In 2015, I was awarded (~13% success rate) with a prestigious Juan de la Cierva-formación post-doc fellowship (Spanish Government). I was ranked the first of 1-to-3 years of experience Spanish post-docs (out of 108) in 2015 in the panel “animal and plant biology and ecology” according to my track record. During this period, I joined the group of biological invasions at IMEDEA-CSIC (Spain), where I have introduced a new dimension in my research by exploring the role of regime shifts in the social-ecological complexity of marine populations. In June 2017, I was awarded (~14% success rate) with a Juan de la Cierva-incorporación fellowship (Spanish Government) to cover my salary of my third post-doctoral stage. In 2017, I was ranked the second of 4-to-6 years of experience Spanish post-docs (out of 103) in the panel “animal and plant biology and ecology” according to my current track record. In August 2019, I was awarded (~7% success rate) with a Tenure Track Grant Ramon y Cajal, the most prestigious post-doc Grant in Spain (Spanish Government, 200k, national funding, 60 months). I was ranked the third of 5-to-12 years of experience Spanish post-docs (out of 257) in the panel “Environmental Sciences and Technology” according to my track record. I was Ramon y Cajal researcher from 01/2020 to 11/2021. Since December 2021 I'm Tenured Researcher (Científico Titular de OPIs) at the Department of Marine Ecology, IMEDEA (CSIC-UIB) and Associate Professor (60 hours per academic year) at the Department of Biology of the UIB.
