Research
Our research focuses on the environmental behavior of radionuclides. Our main goal is to provide valuable data for the remediation of contaminated sites and to ensure the safety of future and existing nuclear waste repositories.
Therefore, we study the mechanisms that affect the migration of radionuclides in the environment, including:
- the study of technetium chemistry, in particular,
- the study of the chemical behaviors of inorganic (minerals) and organic (e.g. humic and fulvic acids) colloids,
- their interaction with the radioisotopes,
- the interactions between radioelements and synthetic and organic ligands.
N. Wall education and past career
- Post-doctoral (Florida State University, FL). Advisor: Prof. G.R. Choppin.
- Doctorate in Sciences (1993), Radioanalytical and Nuclear Chemistry. University of Paris XI (Orsay, France). Advisors: Prof. R. Guillaumont and Dr. V. Moulin
- “Diplôme d'Etudes Approfondies” (DEA) (1990), Radioanalytical and Nuclear Chemistry. University of Paris XI (Orsay, France).
- “Maîtrise de Sciences Physiques” (1989), Chemistry/Physics. University of Paris XI (Orsay, France).
These degrees have been certified equivalent to a PhD in Radiochemistry, a MS in Radiochemistry, and a Bachelor in Physics and Chemistry
N. Wall also worked at Sandia National Laboratories, where she studied the chemistry of the Waste Isolation Pilot Plant (the world first deep underground disposal for transuranic wastes) and in the Department for Radioactive Waste Repository at the Comissariat à l’Energie Atomique (CEA), France.
