Engineering Design and Mathematical Modelling

Professor Nnamdi Nwulu is researcher, educationist and engineer. He holds BSc and MSc degrees in Electrical & Electronic Engineering and a PhD degree in Electrical Engineering. He is currently an Associate Professor in the Department of Electrical & Electronic Engineering Science at the University of Johannesburg. He is also a Professional Engineer registered with the Engineering Council of South Africa (ECSA), an National Research Foundation (NRF) rated researcher, a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE), a Senior Research Associate in the SARChI Chair in Innovation Studies at the Tshwane University of Science and Technology and Associate Editor of the African Journal of Science, Technology, Innovation and Development (AJSTID). Mammo Muchie founded the African Journal on Science, Technology, Innovation and Development (AJSTID) in 2008 and has served as its Editor-in-Chief, ever since. He has been given the Best Institutional Senior Researcher of the Year Merit and the Academic Excellence Award. Professor Muchie’s scholarly contribution to the discipline of innovation has been in strengthening and contextualising the theoretical framework of National Innovation Systems as applied to the African context. Without his work, the principles and theory of the National Innovation Systems, as they are practised in the developed and industrial economies, could not be applied directly to the developing or under-developed and largely agrarian economies of the African continent.
