(2008) degrees at the University of Karlsruhe (now KIT), Germany. As part of his doctoral research he worked on the use of the Ground penetrating radar to retrieve continuous soil water data for climatic applications. Hitherto, most popular soil water information used had been discrete.Prof. Kwasi Preko has over 20 years been lecturing in the Department of Physics (Geophysics, Meteorology and Climate Science Units) of the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi. He has supervised over 100 undergraduate students at the undergraduate level in B.Sc. Physics, Geophysics and Climate Science and Meteorology as well as 50 postgraduate research projects at the MSc/MPhil level in Geophysics and Meteorology and Climate Science, co-supervised 8 PhD students and supervised 10 PhD students in Geophysics and Meteorology and Climate Science. He has over 50 publications in peer-refereed journals to his credit.Prof. Preko is the immediate past Dean of the Faculty of Physical and Computational Sciences of the College of Science, KNUST (2018-2020). He has been Vice-Dean of the same Faculty and Head of Department, Department of Physics (2017 - 2018), and Board Chairman, Photocopy Unit, KNUST, Kumasi (2017 to 2020).
