About Prof Abayneh Ambushe

Prof Abayneh Ataro Ambushe leads his research group that focuses on speciation and monitoring of potentially toxic elements in environmental, biological and food matrices. He investigates the transport and fate of the toxic elements and risks these toxic elements pose to the communities residing in mining areas. He aspires to produce highly trained graduates that can meet the needs of a promptly changing work environment. To prepare students for the real world that they will encounter, he promotes critical thinking and guides them to develop problem-solving skills. Prof Abayneh Ataro Ambushe teaches Analytical Chemistry courses both at undergraduate and postgraduate levels. He leads analytical chemistry research group at Department of Chemical Sciences, Auckland Park Campus, University of Johannesburg. He attracted research funds from Water Research Commission and National Research Foundation, lead research projects, supervised successfully and currently supervising several PhD, MSc and BSc Honours degree research projects, and authored/co-authored a number of articles in peer reviewed international journals. Prof Abayneh Ataro Ambushe is winner of 2019 Water Research Commission Knowledge Tree Award for the impact of his research on the Human Capital Development in the Water and Science Sector.

Highest qualification: PhD

Field(s) of research:

Trace and ultra-trace analysis of potentially toxic elements, speciation analysis, fingerprinting the sources of pollution using stable isotope ratio measurements, food authentication, food safety and related health risk assessment, monitoring organics such as pesticides, polycyclic aromatic hydrocarbons and other emerging pollutants in environmental matrices (water, soil, sediment, vegetables, etc.), wastewater treatment and adsorption studies, phytoremediation and phytomining studies and their applications.
