Research Interests

My research principally focuses on the study of paleoceanography and paleoclimatology with a special emphasis on understanding the origin and mechanisms of abrupt climate change. I estimate past environmental and climatic changes by measuring the geochemical composition of carbonate fossils. I have studied two types of climate archives 1) microfossils deposited in deep-sea sediments and 2) marine bivalves.

1) Ocean sediment records of past climates
Sediment records of the North Atlantic Ocean have revealed the existence of an unstable climate during the last glacial period (~ 60,000 to 10,000 years ago). I combined the use of rock fragment analysis, micropaleontological and geochemical tools to reconstruct past ocean circulation and continental ice sheet behaviour in relation to the evolution of Northern Hemisphere climate during the past 60 000 years.


2) Marine bivalves
I am currently investigating the use of fossil marine molluscs as a tool to reconstruct past climatic evolution. My approach has been to analyse the geochemical variations of annually secreted layers of carbonate to reconstruct past environmental changes of coastal waters. I followed a multi-proxy approach combining measurements of stable isotopes and the abundance of trace elements to differentiate the role of environmental constrains (water temperature and salinity) and physiology (growth rates, ontogenetic evolution) on the geochemistry of the shells carbonates.
