López-Sepulcre CV

Andrés López-Sepulcre



I am an evolutionary ecologist interested in eco-evolutionary theory. I use a combination of theory, short-term experiments, long-term data, and statistical modeling to answer questions regarding two main themes: (1) the feedback between nutrient cycling and life history evolution, and (2) the evolution of dispersal and population spread.
