Department: Animal Experimentation

Administrative Role: Head of Department

Dr. Samuel Adjei earned BSc. (Hons) in Biological Sciences in 1992 from the Kwame Nkrumah University of Science and Technology (KNUST). In 2002, he proceeded to undertake further studies in Nagoya University, Japan where he obtained MSc.and PhD degrees in Applied Molecular Bioscience (Animal Genetics) in 2004 and 2007, respectively.

In 2008, he became a Research Fellow in the Department of Animal Experimentation. Prior to this, he worked as a Research Assistant and assisted in the establishment of well-defined laboratory animals for biomedical research and the development of the grasscutter as a model animal for buruli ulcer research. He has taught Biology at the Advanced and Senior High School Levels for several years and is also a Part-time lecturer in Principles of Genetics (Level 300) and Advanced Genetics (Level 400) in the Department of Animal Biology and Conservation Science, School of Biological Sciences, College of Basic and Applied Sciences, University of Ghana. His specialty training encompasses Laboratory Animal Science (Breeding and quality assurance), Avian influenza molecular diagnostics, and Medical and Experimental Mammalian Genetics. Since 2009 he has collaborated with other researchers and has won several research grants.
