Associate Professor Johan Wesseloo
Director, Australian Centre for Geomechanics
Since obtaining a BEng (Civil) and MEng (Geotechnical) from The University of Pretoria, Johan has been involved in geotechnical engineering in open pit and underground environments throughout 14 countries. He commenced his career in 1998 as a geotechnical engineer at SRK Consulting in Johannesburg where his experience included open pit and underground projects in varying geotechnical conditions. In 2005 he was awarded a PhD (Geotechnical) from The University of Pretoria. Johan joined the ACG in 2007 as a Research Fellow. During his time at the ACG, Johan has been involved in research, the supervision of postgraduate students and geotechnical training. He also performs geotechnical and mining-induced seismicity reviews providing him with the valuable opportunity to visit numerous operations worldwide. Johan was instrumental in the development of the mXrap software and many of the software routines and apps available in that platform. Johan is a Fellow of The Australian Institute of Mining and Metallurgy and the Southern African Institute of Mining and Metallurgy. He was awarded the SAIMM Gold medal in 2006 and 2016, and the SAIMM Silver Medal in 2014. In May 2019, Johan was appointed Centre Director.
William Joughin
Chairman, SRK Consulting, South Africa

William has 29 years of experience in underground rock engineering. William worked on South African deep level gold mines before joining SRK Consulting in 1998. He specialises in underground rock engineering investigation and design, and has published over 40 articles on rock engineering. His expertise encompasses geotechnical investigations, numerical modelling, mining method selection, design of mining excavations, investigation of shaft stability, and geotechnical risk.

William has a special interest in deep, high stress mining and seismic risk. He has provided consultancy services for mining projects on five continents, with various orebody geometries and rock mass characteristics, exploited with a wide range of mining methods. William is a Past President of the South African National Institute of Rock Engineering (SANIRE); the current Vice President for Africa and 1st Vice President of the International Society for Rock Mechanics (ISRM); and a council member of the Southern African Institute of Mining and Metallurgy (SAIMM). He is the recipient of an SAIMM gold medal and the Alec Wilson Award for outstanding papers.

Joseph Mbenza
Research Fellow, Australian Centre for Geomechanics
Joseph joined the ACG in early 2019 as a research fellow. His areas of interest include: advanced numerical modelling and statistical, probability and data analysis. Previously, Joseph was a senior mining geotechnical engineer for SRK Consulting (South Africa) (Pty) Ltd. He has 15 years of experience in mining and rock mechanics.Joseph has a BSc Mining Engineering from University of Lubumbashi, Democratic Republic of the Congo, and a Master’s degree in Rock Engineering from the University of the Witwatersrand, South Africa. He was the recipient of the Rauji Foundation award in 2004 for best student, Faculty of Engineering, University of Lubumbashi, and the Chairman award for employee of the year at SRK Consulting (South Africa) (Pty) Ltd in 2016.
Denisha Sewnun
Research Fellow, Australian Centre for Geomechanics
Denisha has more than 10 years of experience in the rock mechanics aspects of open pit and underground mining projects. She has a BSc (honours) degree in Engineering Geology from the University of KwaZulu-Natal and a Master’s degree in Rock Engineering from the University of Witwatersrand. Denisha has recently joined the Australian Centre for Geomechanics as a Research Fellow after having spent the last 7 years providing consulting services for mining projects across Africa. Her principal areas of expertise include geotechnical data analysis, geotechnical investigations, three-dimensional geotechnical block modelling and rock support design.


This hybrid workshop will be held from 8:00 am to 12:30 pm daily (AWST) from 16 to 19 November 2021.
