Research |
|
Prior to joining Washington State University, I worked at the French Commissariat a l'Energie Atomique (Atomic Energy Agency), in the division for the study of nuclear waste repositories; at Florida State University, on a post-doctoral appointment; and at Sandia National Laboratories, studying the Waste Isolation Pilot Plant, the first deep geological repository for transuranic wastes.
My research focuses on the environmental behavior of radio-contaminants, in particular the actinides. My interest include:
- the study of the chemical behaviors of inorganic (minerals) and organic (e.g. humic and fulvic acids) colloids,
- their interaction with the actinides,
- the evolution of the post-closure chemical environment of a nuclear waste repository,
- the impact of the repository on the solubility and speciation of actinides.
I currently study the interaction of actinides with uranyl minerals (boltwoodite, sklodowskite, and uranophane), minerals predicted to form in the vicinity of a nuclear waste repository,
upon corrosion of the spent nuclear fuel
