Brief Introduction about main academic achievements and key publications

Prof. Amer was the previous dean of Environment and Natural Materials Research Institute (ENMRI) for 10 years. She has efficiently achieved the goals of her organization by establishing a new environmental ENMRI, and obtaining the accreditation of ISO 17025 for the Central laboratory of Environmental Services. She is concerned with solving environmental issues using microbial solutions and bioremediations for water pollution treatment and for sustainable utilization of natural water resources. Prof. Amer leads many national and international projects in different environmental aspects, focusing on finding solution for environmental problems such as water scarcity, solid waste management and supporting the community with tackling their own issues and finding small scale solutions. She is supervising many PhD and master students nationally and internationally.
