Dr. Evans Manu – Consultant Hydrogeologist/Geophysicist (BSc Physics, MSc Geophysics, Ph.D. Hydrogeology)

Dr. Evans Manu is a distinguished hydrogeologist and geophysicist, boasting over a decade of expertise in aquifer hydraulics evaluation, groundwater flow and contaminant transport modelling, hydrogeochemical modelling, and geophysical site investigations using State of the Art methods. Holding a PhD in Hydrogeology from the University of Potsdam, Germany, a Master of Science in Geophysics, and a Bachelor of Science in Physics from the Kwame Nkrumah University of Science and Technology and University of Cape Coast, respectively, Dr. Manu exemplifies a strong interdisciplinary approach and a robust background in water resource management.

During his tenure as a Research Associate at the Fluid Systems Modelling section of the GFZ German Research Centre for Geosciences in Potsdam from October 2019 to December 2023, Dr. Manu applied reactive transport models using PHREEQC to simulate groundwater quality changes, developed innovative geochemical combinatorial inverse models using R, and conducted extensive field investigations and laboratory measurements.

Previously, as a Research Scientist at CSIR – Water Research Institute in Accra, Ghana, from June 2012 to October 2019, Dr. Manu led several hydrogeological research projects with significant impact. Notable research projects include using ground penetrating radar to delineate zones of gold mineralization at the Subenso concession of Newmont Ghana Gold Limited. Additionally, his work assessing the groundwater potential of the Kintampo North municipality of the Brong Ahafo region of Ghana using electromagnetic and vertical electrical sounding methods has contributed significantly to regional water resource management.

Dr. Manu’s extensive training includes a recent certification in Data Science and Machine Learning from Massachusetts Institute of Technology (MIT – USA), enhancing his ability to integrate sophisticated analytical models into hydrogeological research. His proficiency in a suite of technical skills—including Python, ArcGIS, MODFLOW, and PHREEQC—and his soft skills in project management, adaptability, and leadership enable him to handle complex water resource management projects effectively.

Dr. Manu is a dynamic force within the scientific community, having published 13 papers in international journals that boast considerable impact factors. His research primarily explores groundwater flow, contaminant transport, and hydrogeochemical characterization, substantially progressing the field of hydrogeology. His expertise extends to the application of machine learning models in building predictive models that enhance the sustainability of water resource management. He is affiliated with several professional organizations, including the American Geophysical Union, the European Geoscience Union, the Society of Exploration Geophysicists, and the International Association of Hydrogeologists (IAH).
