Lionel Guidi to give Plenary Session Talk at ASLO meeting in Honolulu

Lionel GuidiNouvelle fenêtre of the Laboratoire d'Océanographique de Villefranche-sur-Mer has been invited by the Association for the Sciences of Limnology and Oceanography to give a Plenary Address at the Aquatic Sciences Meeting in HonoluluNouvelle fenêtre, Hawaii (Feb. 26 - Mar. 3 2017). He will be joining a distinguished group of plenary session speakers: Marcia McNutt, President of the National Academy of Sciences, David Karl of the University of Hawaii, Margaret Palmer of the University of Maryland, and Ruth Gates of the University of Hawaii.

Presentation Title:Tara Oceans: The Biological Carbon Pump from Genes to Ecosystems

Presentation Description: The Tara Oceans expedition (2009-2013) is the largest DNA sequencing effort ever done for the ocean revealing around 40 million genes, the vast majority of which are new to science, thus hinting towards a much broader biodiversity of plankton (from viruses to eukaryotes) than previously suggested. Thanks to novel computer models, these data also allowed to predict how these diverse planktonic organisms interact. These resources provided a unique opportunity to look at the biological carbon pump integrating its entire biological complexity, describing the first "planktonic social network" associated with carbon export in the oligoptrophic ocean.

Biographical Information: Lionel Guidi has been a CNRS researcher since 2013 in Villefranche-sur-Mer, one of the three marine stations of the Université Pierre et Marie Curie (Paris 06) in France. He graduated in 2008 from the Sorbonne Universités, UPMC, Université Paris 06, and Texas A&M University in Texas, USA. Shortly after graduation, he started four years of postdoctoral research at the C-MORE (Center for Microbial Oceanography: Research and Education) at the University of Hawaii. Guidi's main research interests are driven by the need to better understand the global carbon cycle, and, in particular, the biological carbon pump, from gene to the ecosystem level. In order to achieve that goal, he had early motivation to bring "standard methods" together with new instruments and analytical tools to study the biology and biogeochemistry of the ocean.
