Biography:

Harry M. Ngwangwa graduated with BSc in Mechanical Engineering from the University of Malawi in 1995 after which he started lecturing in the Department of Mechanical Engineering up to 2002. He obtained his MSc in Structural Dynamics from University of Pretoria in 2005. He completed his Doctor of Philosophy in Mechanical Engineering at the University of Pretoria in 2014. He has lectured and provided short-term training in wide ranging areas of engineering including: Engineering Dynamics, Control Systems, Computer-Aided Designing, Applied Mechanical Science and Project Management. He has also served as a Student Projects Coordinator, ad hoc Faculty Examinations Officer, Faculty Representative on Publications, Short Courses Coordinator and Treasurer for Mechanical Engineering Department at the University of Malawi. He presently works as a senior lecturer in the Department of Mechanical Engineering at University of South Africa.
