The aim of my research is to understand how corals precipitate mineral (i.e. a calcium carbonate skeleton). This biologically controlled precipitation, called biomineralization, is poorly understood because it results from highly complex, dynamic, and coordinated biophysical and biochemical processes. The two main approaches I use are based on experimental models, and on the chemical and structural characterization of stony corals. The experimental models are based on coral cell cultures that mimic the coral biomineralization process within a simple laboratory model. I am using imaging techniques including fluorescent microscopy applied to this laboratory model to visualize the mineral precipitation at the cellular level. In terms of the stony corals, I am using a set of advanced techniques including both spectroscopic (solid-state NMR, RAMAN) and microscopic (scanning helium ion microscopy, TEM) tools. Once combined together, a precise structural characterization of the mineral is possible (both the newly formed and the mature mineral), while the solid-state NMR is a suitable tool to study the mineral/organic interface.
I received my B.S in chemistry in 2009 and my M.S. in chemistry of Materials in 2011 from the University Pierre and Marie Curie (UPMC), Paris. My first encounter with the field of biomineralization was at the University of Florida in 2011 while completing the "Research Experiences for Undergraduates" (REU) program - where I was doing research on the urinary stones formation. Subsequently, I continued my research in biomineralization during my Ph.D at College de France in Paris (obtained in 2014) - where I was doing research in the understanding of the bone biomineralization process.
