Research interests
Mostly related to biogeochemistry and Quaternary climate
variations. I also have an interest in understanding the
development and evolution of volcanic systems.
I have a special interest in using the so-called
"non-traditionnal" stable isotopes like Zn, Cu or Fe to understand
various biogeological systems, especially micronutrients transfers
between soils and plants and within plants.
I also use U-series for both paleoclimate (North Atlantic,
Equatorial Pacific) and volcanological (Mount Erebus, Crozet)
applications. My main interests are: the reconstruction of past
variations in the intensity of the Atlantic Meridional Overturning
Circulation (AMOC) using (
231Pa/
230Th)
xs,0, the
reconstruction
of paleo-fluxes using
230Th-normalization.
I
also use Pb isotopes to trace the variations in the origins of
dust in the Equatorial Pacific (e.g. Pichat et al.,
2014).

Teaching
I'm in charge of the Master of the Département de Sciences de la Terre
(ENS Lyon - University Lyon 1)
I'm teaching ca. 200h/year in various subjects of Earth
Sciences.
I'm also in charge of 6 U.E. (teaching units):
- Cartographie et méthodes de terrain
(L3) - Field mapping
- Sismique en mer (L3) - Methods of
seismology at sea. Blog
of the research/student cruises MAGIRAA
- Actualités et synthè
ses
en Sciences de la Terre (M1) - News in Earth Sciences
- Océanographie (M1) - Oceanography
- Analyses élémentaires et isotopiques (M1) -
Elemental and isotopic analyses in Earth Sciences
- Experimentations en géochimie (M1) - Geochemical
experimentation and applications in the lab
I also give lectures at the:
- Dept of Biology (The cycle of micronutrients between soils
and plants)
- Dept of Physics (Geochemistry and paleoclimatology)
- "Préparation à l'agrégation" (Atmosphere and Oceans;
Quaternary paleoclimates)
- Open
university program of the Université Lyon 1 (The time in Geology)
I've also been
teaching during the 4 years of my PhD. I gave 24h/year
lectures in physical oceanography and I also lead field
trips with students from the former Magistère of Earth
Sciences.
- Summary of my
lectures (in french)
- Pictures from a field trip in the Corbières/Pyrenees
area (September 1999).
