Prof. Onwona‐Agyeman obtained his BSc degree in Physics at KNUST in 1994 and was awarded the Japanese Government Scholarship to study the MSc and Ph.D. degrees in Physics (Experimental Condensed Matter Physics) and Materials Science & Engineering respectively from 1997 to 2002.

He was offered a Postdoctoral position with Shizuoka National University in Japan from 2003 to 2005. After the Postdoctoral appointment, he was employed as a Scientist with the SPD Lab, Inc. in Japan from 2005 to 2007 where he worked on the development of large‐area dye‐sensitized solar cells. In 2007, he was recruited to join a team of scientists and engineers (collaboration between Japanese Govt, FCC Company and Honda Motors) to develop porous‐structured catalyst paper for purifying exhaust gas emissions from small internal combustion engines and for hydrogen production using methane steam reformation. From 2009 to 2012, he worked as Research Associate and Assistant Professor at Kyushu Institute of Technology and Kyushu University respectively in Japan before joining University of Ghana in 2013.
