Dr.Marian Asantewah Nkansah, a Senior lecturer at the Department of Chemistry at the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi; was born in the late seventies in Ghana to Mary and Joseph Nkansah both educationists. She has three brothers and two sisters. Marian started her basic school in St. Anthony’s Experimental School, Nkawkaw in the Eastern Region of Ghana. Prior to her university education, she majored in Science at the St. Roses’ Secondary School, Akwatia-Ghana; one of the most prestigious High Schools for girls in Ghana. She holds a PhD in Environmental Chemistry from the University of Bergen-Norway and obtained her BSc. and MSc. from KNUST in 2002 and 2005 respectively. She teaches Practical Chemistry, Nuclear/Radiochemistry, Chemistry and Society, and Petroleum Chemistry. Marian has been a faculty member since January 2007. Her research interests span a wide range of fields including finding solutions to environmental problems associated with levels and fate of toxic substances like heavy/trace metals, persistent organic pollutants (POPs) and polycyclic aromatic hydrocarbons (PAHs) in food, water, soil, rocks, sediments and other environmental samples and the interaction of these pollutants with each other in the environment. She has a number of peer reviewed articles and books to her credit. Her research work in Environmental Chemistry, especially in the areas of contamination and pollution of the environment by toxic substances, has set a high standard in bringing public awareness to researchers and civil society. She serves as reviewer to a number of local and international journals. She is a member the Ghana Young Academy and affiliate of the African Academy of Sciences. She was named the inaugural recipient of the FM Al-Kharafi TWAS Prize in 2016.
