Profile 

Dr. Agyekum is a Principal Research Scientist at the Water Research Institute of the Council for Scientific and Industrial Research (CSIR-WRI). He obtained his bachelor’s degree in Geological Engineering from the Kwame Nkrumah University of Science & Technology (KNUST, Kumasi) in 1989, Master’s degree in Groundwater Hydrology at the International Institute for Infrastructural, Hydraulics and Environmental Engineering (IHE), Delft, The Netherlands in 1998; and PhD in Hydrogeology at the University of Ghana in 2009.

He is a seasoned Hydrogeologist and Geophysicist who has worked on many groundwater-related projects throughout the country since 1991. He has undertaken various groundwater projects for governmental agencies and on several donor-funded projects including CWSA, Water Resources Commission, Danida, Kruger Consult, CIDA-HAP, DFID. He has work experience in Liberia, Sierra Leone, and Burkina-Faso. Dr. Agyekum has gained considerable experience in the areas of research and in-depth knowledge in Groundwater Resources Assessment, Geophysical Exploration, Borehole Construction and Design, Borehole Geo-logging and Pumping Test and Aquifer Evaluation.

In terms of groundwater assessment, Dr. Agyekum is an expert in pumping test and aquifer evaluation using the classical Theis and Cooper-Jacob analytical methods, as well as the use of the modern Aquitest Software. Furthermore, Dr. Agyekum is an expert in borehole geo-logging, using HRFM, GLOG, DUIN, TCGS, and 3ACS logging tools. He has supervised many post-graduate students at the Masters and MPhil programs in several Ghanaian Universities.

He is also a reviewer for some international peer-reviewed journals including Journal of African Earth Science (AES), International Journal of Climate Change Strategies and Management (IJCCMS) and Physics & Chemistry of the Earth (JPCE). He has obtained many research grants from funding agencies including the NUFFIC, DFID and ENRECA/DANIDA. He has published over 20 peer-reviewed articles in international journals.
