Nathalie Malengreau

Nathalie Malengreau is a Researcher at the University of Namur (UNamur), Belgium, specializing in soil science and materials chemistry. She holds a PhD in research administration and actively leads and supports interdisciplinary projects focused on environmental sustainability and technological innovation.

Her educational background includes a 1994 doctoral thesis titled "Approche par spectroscopie optique des statuts du fer et du titane dans les matériaux kaolinitiques. Application au traçage des processus d'altération et érosion en régions tropicales humides." (Optical spectroscopy analysis of iron and titanium status in kaolinitic materials, applied to tracing alteration and erosion processes in humid tropical regions).

Dr. Malengreau's research centers on mineralogical and geochemical processes in tropical soils, with expertise in kaolinite dissolution mechanisms, iron speciation, and clay mineral behavior. Her work extends to nuclear waste management (glass stability in geological disposal) and environmental remediation (pesticide degradation on manganese oxides). Recent projects emphasize sustainable materials and alternatives to animal testing.

Analysis of her publication history reveals consistent focus on colloidal phenomena in soil systems and material-environment interactions, bridging fundamental geochemistry with applied environmental challenges. Her research directly contributes to UN Sustainable Development Goals related to clean water, responsible consumption, and climate action.

She has secured significant research funding through multiple competitive grants:

• Principal Investigator for "Grant for activities to support research and internationalization at UNamur" (2022-2023)
• Support role in "Technological Platform of Excellence 'Alternatives to Animal Experiments'" (2022-2024)
• Support role in "PTE BioGreen: 'BIOGREEN' Technological Platform of Excellence" (2022-2024)

Dr. Malengreau maintains active external collaborations with Materia Nova Research Center and CENTEXBEL, as documented by institutional visits in 2019. Her work integrates into broader Walloon and Brussels regional research networks focused on green technology and sustainable materials development.
