I am an evolutionary ecologist raised in Spain, with a PhD in Finland who has worked as a scientist in California, France, St. Louis, and now Cornell. In  am interested in a variety of ecological and evolutionary questions, especially involving the relationship between both disciplines and the theory of eco-evolutionary feedbacks. For the most part, I do my research on Trinidadian guppies (Poecilia reticulata) and the tropical streams they live in, but I am curiosity-driven and sometimes foray into other species and systems. My background is largely quantitative but I like to approach questions in an integrative manner, through a combination of mathematical models (statistical or theoretical) long-term data, and manipulative experiments in the field, laboratory, and semi-natural environments (mesocosms). 

Some of my current research questions include: (1) How does adaptation to density and resource availability affect nutrient cycling, and how does in turn affect the evolution of guppy life history, stoichiometry, trophic ecology, and ecophysiology? (2) How does dispersal evolve as populations spread and how does this affect their invasiveness? (3) What are the demographic and evolutionary consequences of density-dependent selection? (4) How predictable and repeatable are rapid evolution and its ecosystem effects? and (5) How do eco-evolutionary feedbacks function in urban environments?

When I am not doing research or teaching, I like spending time with my children, birdwatching, or building self-sustaining ecosystems in glass tanks. I also love traveling, pretending I can speak languages, eating good food, and drinking good wine.
