Profile: DR. EMMANUEL KABOJA MAGNA

Dr. Emmanuel Kaboja Magna serves as a Research Scientist within the Fisheries and Aquaculture Division of the Council for Scientific and Industrial Research – Water Research Institute (CSIR-WRI). He earned his Bachelor’s degree in Biological Sciences, specializing in Oceanography and Fisheries, from the University of Ghana in 2007. Subsequently, he obtained a Master’s degree in Health Informatics in 2014 from the Kwame Nkrumah University of Science and Technology, Ghana. In 2020, he completed his PhD in Environmental Science at the Institute for Environment and Sanitation Studies (IESS), University of Ghana, where his doctoral research focused on the “Ecological and Human Health Implications of Contaminants Linked with Cage Aquaculture on the Volta Basin of Ghana.”

His research identified varying concentrations of indicator polychlorinated biphenyls, organochlorine pesticides, and heavy metals in water, sediment, and cage-cultured tilapia. It further assessed the ecological risks and pollution status of sediments, as well as the health risks associated with human consumption of these fish. Dr. Magna has also conducted significant research in areas such as solid waste management, the effects of climatic variables on crop yield, malaria distribution, and a comprehensive review of Ghana’s mental health policy. His doctoral thesis, along with other research endeavours, has resulted in thirteen (13) publications in esteemed peer-reviewed international journals.

In addition to his primary responsibilities at CSIR-WRI, Dr Magna has engaged in various research initiatives concerning pesticides, antibiotics, PBDEs, and PAHs across diverse environmental matrices, as well as wastewater quality treatment and reuse. His exceptional research curiosity and capabilities have been consistently demonstrated throughout these projects. He is recognized for his innovative approach and possesses significant intellectual acumen. Dr. Magna has co-supervised undergraduate students at several Ghanaian universities and serves as a reviewer for numerous international peer-reviewed journals. Furthermore, he has taught at the senior high school level for about eight years and is currently an Adjunct Lecturer in the Department of Aquaculture & Fisheries Science at the University for Development Studies (UDS) in Nyankpala, Tamale..

Research Interests

His research interests include but are not limited to, aquaculture, environmental health, EIA, water quality monitoring and assessment, toxicological assessment of low-dose heavy metals and persistent organic pollutants (Pesticides, PAHs, PCBs, PBDEs and antibiotics) in different matrices, as well as their associated human health risks.
