Yusef received his PhD in Environmental Science from the University of Copenhagen in Denmark, June 2017. During his PhD project, Yusef spent around 20 months at the Institute of Soil Science, Chinese Academy of Sciences in Nanjing, 2014 to 2016, working on phosphate bonding and phosphate biogeochemistry in Chinese greenhouse vegetable soils. From July 2017 to March 2018, he was visiting scholar at the University of Copenhagen. Afterwards, he was a lecturer at Anhui Agricultural University for over four years before becoming an assistant professor at Wenzhou-Kean University in August 2022. Over the courses of his education and employment, Yusef has been involved in several projects focusing on different aspects of Environmental and Soil Sciences with over 40 publications in international reputable journals. Overall, he is very interested in investigating the biogeochemical cycling, translocation, and speciation of nutrients, trace metals, and organic pollutants in terrestrial and aquatic environments. His interest also includes Environmental Risk Assessment (soil and water quality/health assessment; Human health exposure to contaminants via food consumption), Water Treatment (Biochemical and physical removal of water contaminants, phosphorus recovery and reuse, and drinking water), and Sustainable farming (no-till or reduced-till, green manure application, multiple cropping, efficient water management).
