du Toit, Madeleine

Overview

Madeleine du Toit joined the University of Wollongong as Professor in the Welding Engineering Research Group within the School of Mechanical, Materials, Mechatronic and Biomedical Engineering in 2014, and has since been appointed as Program Leader for Research Program 1 (More efficient use of materials for energy pipelines) in the Energy Pipelines CRC. Madeleine holds BEng, MEng and PhD degrees in Metallurgical Engineering from the University of Pretoria in South Africa and a Masters degree in Welding Engineering from the University of the Witwatersrand. She is a registered Professional Engineer, a qualified International Welding Engineer (IWE) and a Certified Materials Professional (CMatP) with Materials Australia. She served as President and member of Council of the Southern African Institute of Welding (SAIW) from 2010 to 2014, and as Chairperson of the Governing Board of SAIW Certification (responsible for the assessment and certification of welding personnel in South Africa) from 2005 to 2014. She is currently a member of the board of Directors of Weld Australia and a member of the National Council of Materials Australia. Madeleine was actively involved in the activities of the International Institute of Welding (IIW) as part of the Australian delegation - as Chair of Commission IX (Behaviour of metals subjected to welding), Chair of Working Group Communications & Marketing and as member of the Study Group for Welding Research and Strategy. Since 2011 she has established successful internationally accredited training programs for International Welding Engineers and International Welding Technologists in South Africa and in Australia.
