Marquet (PhD, 1993, University of New Mexico, Albuquerque, USA) is Professor at the Departmento de Ecología, Facultad de Ciencias Biológicas, Pontificia Universidad Católica de Chile in Santiago and External Faculty of the Santa Fe Institute (USA). His work has focused on the quest for general principles underlying the complexity of ecological systems, the impacts of Global Change on biodiversity, the integration of theories in ecology and the ecological basis of human social complexity. His works on scaling relationships and on species diversity and size evolution on islands, provided an explicit and novel connection between allometric scaling, island biogeography and evolution. These findings paved the way for later developments in macroecology and metabolic ecology and a deeper understanding of the extent to which our society is sequestering energy from the biosphere to fuel social complexity. He was a Guggenheim Fellow and is currently member of the Chilean Academy of Sciences, Foreign Associate of the National Academy of Sciences (USA), International Honorary Member of the American Academy of Arts and Sciences and Fellow of the Ecological Society of America.
