Biography:

I  obtained my  Ph.D at  the University of Bordeaux I in 1997, before coming to Cambridge as a post-doc in the Godwin Laboratory under the supervision of Professor Shackleton. Over the years I have worked on many research projects all aimed at either directly reconstructing oceanographic palaeoenvironmental changes and palaeoclimates from deep-sea sediments or assisting with such reconstructions led by collaborators.

I  work on  coarse sedimentary fractions >150 microns, which contain mainly foraminifera and other biological components as well as lithogenic (detrital or volcanic) or authigenic particles. 

I  work on  a binocular light microscope several hours every day. I  observe, record my observations, count the various components or pick foraminifera per species and size ready for various geochemical analysis. 

Firstly, I am an expert in planktonic foraminiferal assemblages over the Quaternary. I perform and focuse on foraminifera assemblages counts to be used in palaeoceanographic studies as well as in the  biostratigraphic assessment of older samples (over the all Cenozoic) when necessary. My work also involves assessing the preservation state of deep-sea carbonates found in the sediments through the examination or the point counting of foraminifera shells and fragments (or other proxies). I  also routinely  examine coarse fractions for major sedimentary constituents such as ice-rafted debris tracing  major cooling in middle latitudes. I  am also able with benthic foraminifera assemblages , which  trace changes in  the deep-water properties, although I have a lesser track record on this.

Beyond my micropaleontological studies either environmental or biostratigraphical, my skills with foraminifera are routinely used for the preparations of all types of necessary samples for isotopic studies, either aimed at uncovering  palaeoceanographic changes or the establishment of detailed Oxygen isotopic stratigraphy.  Further to all the technical preparations that my daily work involved I  am  trained at  interpreting  Oxygen and Carbon isotopes measured in foraminiferal calcite. I  am  also  trained in the preparation and interpretation in major trace metals in foraminiferal calcite, such as Mg used in Mg/Ca thermometry.

 I  am  currently  working  on  two  major projects.

1. The establishment  of a detailed  (centennial-scale) isotopic stratigraphy of IODP Site U1385 over the Quaternary

This Site, is also called the Shackleton Site, in memory of my former supervisor Sir Nick Shackleton and was drilled 5  years ago under the leadership of Professor Hodell, who is the principal investigator of the project. I am expertly although very routinely supporting him technically on this high profile yet tedious and demanding project. 

2. The development of a promising and fairly new method and its application to foraminifera. I  am  focusing on helping with my  skills and experience of foraminifera with the development of paired clumped isotopes and Mg/Ca analysis from the same foraminifera phase. I  am preparing all the samples, hand picking a number of  large mono- specific samples, cleaning them in the clean lab and precisely weighing the numerous aliquots to be used on in the mass spectrometer. I do  this from both surface samples and down core samples.

3. Previously

In 2014, I  sailed as a biostratigrapher and foraminifera expert on IODP leg 350 South of Japan. This research is now being  finalized but I  am  still working on some personal research as well as collaborating with other scientists part of the drilling expedition.

Between mid 2012 and end 2013, I  was helping colleagues of the department with the skill-full preparation of large mono-specific planktonic foraminifera samples for Boron and Sulphur isotopes over a long  suit  of samples covering the whole Cenozoic and the Upper Cretaceous  (0-to 68 ma). This from a set of good quality and well-studied DSDP/ODP/IODP Site at a resolution c. 0.3 ma.  

Prior to that, funded by NERC, I carried out a feasibly study for a future IODP Leg off the Antarctic Peninsula. Leg, which should be scheduled fairly soon. In 2009-2010, I  collaborated on the study of  TNo-57-21 in  the South  Atlantic with Professor S. Barker (Cardiff) and other colleagues.

 In addition, I  worked for 5 years at the BAS in Cambridge as a micropalaleontologist before my post was made redundant.

Prior to  that (1999-2003), I  held several  post-doctoral research contracts as a micropaleontologist based in the Godwin Laboratory
