Dr. Not, Christelle

Senior Lecturer

I am a geochemist interested in trace element and radiogenic isotopes behavior in aquatic environments over short and long time scale. My research interest focus on the understanding of trace elements cycles, such as Sr, Ba, Ra, U, Th, Nd, Pb in ocean and their utility as proxies in paleoceanography. I am particularly interested in the understanding of the behavior of these elements during their transfer from land to ocean with a focus of the importance of groundwater, their incorporation to micro-organisms, their behavior during scavenging process and their use as paleoceanography proxies in a paleoclimate perspective.
