Biography
Nadejda Andreev was born in 1972. She obtained her Bachelor of Science in Biology from Moldova State University, Faculty of Biology and Soil Sciences in 1994, and her MSc degree in 1998 at the Central European University in Environmental Sciences and Policy and also obtained a second MSc degree in Biodiversity at Swedish University of Agricultural Sciences in 2004. Dadejda is currently employed as a Leading Researcher in the Laboratory of Hydrobiology and Ecotoxicology, Institute of Zoology, Academy of Sciences of Moldova, and leads an NGO which implements projects related to decentralized sustainable technologies including sustainable sanitation.
She carried out her PhD studies at UNESCO-IHE Institute for Water Education, (Delft, the Netherlands) between 2011 and 2016. Her research interests include eco-friendly and cost effective treatment and reuse of human excreta, especially in agricultural applications. Nadejda’s PhD research topic focusses on terra preta sanitation and its applications in agriculture and urine diverting dry toilets.
