Philippe Bertrand is physical chemist. He conducted his research career at CNRS (Centre National de la Recherche Scientifique, the main French research organization). His main research topics are paleoceanography and paleoclimatology.
His research has focused on the relationships between the activity of coastal upwellings systems and climatic variations in the last glacial-interglacial cycles. He then became interested in the functioning of the Earth System as a whole, and devoted to this topic his book Les attracteurs de Gaia and many other publications.
For several years, Philippe was director of research unit EPOC, after which he supervised the research carried out by CNRS in the fields of ocean, atmosphere and climate (around 30 research units and observatories), which further strengthened his interdisciplinary background. It also reinforced his wish to link information from several disciplines to analyze the dynamic complexity and evolution of the Earth System over 4.6 billion years.
He is a dedicated amateur photographer of the natural environment.
