Expertise: Environmental Microbiology, Environmental Toxicology, Toxicity Bioassays, Bacterial Bioremediation, Construction Materials Biocolonization
Short Bio:
Cristina A. Viegas is a researcher in biological sciences, mostly dedicated to environmental microbiology and toxicology fields. She has a graduation in Chemical Engineering - Chemistry and Processes (IST; 1984), a Master in Biotechnology - Biochemical Engineering (IST; 1988), a PhD in Biotechnology (IST; 1993) and a Post-Doc in Molecular Microbiology (Institute of Virology and Environmental Microbiology, Oxford, UK; 1995). In the last years, her research mostly addressed yeast-based bioassays for the assessment of potential toxicity of pesticides and environmental samples, bacterial biodegradation and bioremediation of herbicide contaminated sites and phylogenetic characterization of microbial communities in building façade biocolonization stains.
