Prof. Abdur-Rahim Adebisi Giwa is a seasoned academic with specialization in Analytical/Environmental Chemistry. He has been able to conduct researches on environmental pollution monitoring and remediation using low-cost materials. While there have been many studies on the removal of contaminants from aqueous solutions with, in most cases, attention on only a single toxicant at a time, his efforts have been focused mainly on the removal of co-existing (mixture of) contaminants in wastewater, and the toxicity of the effluent after adsorptive treatment; a novelty.
In addition, he has workedon real industrial effluents such as from textile and food industries. Attempts have also been made by him to prepare ecofriendly corrosion inhibitors from extracts of plant materials such as Negro pepper.
Prof. Giwa’s PhD thesis won the overall best prize for 2012/2013 session in LAUTECH. He was awarded postdoctoral fellowship in Cape Pennisula University of Technology, Bellville, South Africa between 2015 and 2018 where he won a grant under the university research fund of the university to conduct research on wastewater treatment. He teaches at undergraduate and postgraduate levels. He has successfully supervised 3 PhD and 6 M. Tech. and over 100 undergraduate students, many of whom are established in their various careers including academia. He is a mentor to many former and present students within and outside LAUTECH, both on academics and extra-curricular endeavors.
Apart from being a two-term Deputy Dean of the Faculty of Pure and Applied Sciences, he has also served at different levels of university administration either as chairman or member of various committees including Faculty Postgraduate Seminar and Abstract Review Committees.
Prof. Giwa belongs to many academic associations including Chemical Society of Nigeria, Society for Environmental Toxicology and Chemistry, American Chemical Society, and Institute of Chartered Chemists of Nigeria
