Jérémie Gaillot is Head of Biostratigraphy Team in TOTAL S.A., Pau, France. He received his MSc in Biodiversity of present-day and fossil ecosystems in 2002 from the University of Science and Technology, Lille, France. After his work on the Biostratigraphy and Palaeoecology of the Khuff Formation of the Arabian Platform at the University of Lille 1, under the supervision of Daniel Vachard, Jérémie received his PhD degree and joined TOTAL in 2006, as a biostratigrapher. In 2008, he moved on to geological operations on the rigsite first in Libya, then North Sea and finally Russia. From 2010 to 2013, Jeremie was office-based in Pointe-Noire, in Congo-Brazaville's subsidiary, as an Exploration geologist. In 2013, Jérémie returned to his specialized area of expertise, foraminiferal biostratigraphy. He's currently in charge of all the biostratigraphic studies realized at TOTAL's Pau Scientific Center.
