Scientist presentation

Lancelot Christiane
Professor, Dr

Dr. C. Lancelot, head of ESA since 1997 has published some 80 peer-reviewed papers on marine phytoplankton ecology and planktonic ecosystem modeling. She is member of the scientific committee of the SCOR-working group on “Marine phytoplankton and Global Climate Regulation: the Phaeocystis species cluster as model” and part of the EU network Lifehab on phytoplankton life cycles. More generally she is member of several international committees and has been selected by EU as EAG (External Advisory Group) member for the Key Actions Water and Marine Ecosystems implemented in the scope of Framework program 5 (FP-5)
Dr Lancelot is active in polar research since 1987 and is regularly invited to give keynote presentation and chair sessions at international conferences. As international recognition of her work in this field she was chosen in 1997 as European representative in the scientific committee of the Gordon Conference on Polar Marine Science. In March 2001 she has been nominated vice-chair of the 2003 Gordon Conference. She was also member of the SO-JGOFS planning group and of the French PROOF Programme. At the national level Dr. C. Lancelot is member the Comité National belge pour les Recherches dans l'Antarctique.
