Position (last update 2013)

Oct 2010-Oct 2013, PhD student in Paleoclimate modelling at LSCE.
PhD thesis: Climate variability of the late Pliocene warm period (3.3 to 3 Ma): modelling the Greenland Ice Sheet and Megalake Chad variations. Supervisors: Gilles Ramstein (LSCE) & Anne Jost (Sisyphe).

Abstract: The late Pliocene warm period is a crucial interval in climate history and human evolution. Some regional features are poorly constrained for this period: a major one is the Greenland Ice Sheet (GrIS). I investigate the response of the GrIS to different simulated late Pliocene climates, emphasizing on the CO2 and insolation thresholds allowing the build up of the ice sheet. Another important feature is the occurence of Megalake Chad (MLC): I investigate the variability of the MLC and its impact on the local environment in order to understand how its rise up and demise could have influenced hominid evolution during the early stages of humanity.

Research Interests

Climate modelling of the late Pliocene using LMDZ5 and IPSL-CM5A GCMs.

Megalake Chad impact on late Pliocene and mid-Holocene climates.

Constraining Megalake Chad variations with orbital variations, and the corresponding changes in hominids habitats during the mid-Piacenzian.

Caracterizing CO2 and insolation thresholds for the build-up and maintain of the Greenland Ice Sheet during the Piacenzian.

Previous Research Experience

Feb-Sept 2010: Undergraduate Research Assistant at Université Pierrre et Marie Curie, Paris 6. Thesis: Response of deep aquitards of the Paris Basin to anthropogenic pumping forcing in the Albian aquifer: integrating forcing and  calibrating the 3D groundwater flow model. Supervisor: Sophie Violette.

May-Aug 2009: Undergraduate Field and Research Assistant, Institut de Recherche pour le Développement, Lima, Peru. Based in Tamshiyacu (Loreto), I carried out two fields campaigns for the measure of high river discharge at the birth of the Amazon river (confluence Marañon-Ucayali). Afterwards, based in Lima, I analysed discharges throughout the years and calculated the uncertainty on the rating curves and thus on the water balance at the confluence. Supervisors: A. Crave, P. Fraizy, P. Vauchel.
