(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.

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).
