He is currently participates in several geotechnical review boards.
PMD_web_small Phil Dight
Professor Geotechnical Engineering
Australian Centre for Geomechanics
Phil has been involved with the development and design of ground support for mining applications since 1975. He was a partner in BFP Consultants until BFP was acquired by Coffey Mining. Phil has extensive consulting experience in the geotechnical aspects of the mining industry, and has worked on open pit and underground metalliferous mining problems. In 1985, he was awarded the Manuel Rocha Medal by the International Society of Rock Mechanics for his work in open pit mining and use of ground support to improve pit stability. His ground support algorithm has been adopted by Rocscience in its evaluation of ground support in phases. With Peter Fuller he undertook research into ground support in a number of AMIRA sponsored projects. Much of that early research work has now been formalised in literature by others. Phil joined the ACG in 2008, and has since been working on stress memory effects in rocks, influence of deformation anisotropy on stability of underground openings, ground support applications and slope stability problems.

SRK Consulting (SA) (Pty) Ltd, South Africa
William has spent the past 25 years in the field of underground rock engineering, having worked for South Africa’s largest gold mining companies before joining SRK Consulting in 1998. As chairman at SRK, 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 layouts, investigation of shaft stability and geotechnical 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 Institute of Rock Engineering; the current vice president for Africa and 1st vice president of the International Society for Rock Mechanics; 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.
Sweby_Gordon Gordon Sweby
Senior Research Engineer
Australian Centre for Geomechanics
Gordon joined the ACG in early 2014 as a senior research engineer for the ACG’s premier research project, “Ground Support Systems Optimisation” and will focus on the application of numerical models for ground support design. Gordon is a rock engineering professional with 27 years of experience. He graduated from the University of the Witwatersrand in 1984 with a BSc Geological Engineering, and then obtained a Masters in Rock Mechanics, also from Wits, in 1994. Gordon has the Chamber of Mines (South Africa) Certificate in Rock Mechanics (coal and metalliferous) and is a registered professional engineer with the Engineering Council of South Africa. He has practised as an operations engineer in both open pit and underground environments. In more recent times has held a corporate role as group geotechnical engineer for a multinational mining house. Additionally, Gordon has experience in a consulting environment, both as an independent and for various consultancy companies. Practical and technical expertise includes ground support design, mine seismicity, mine design and sequencing, ground control and safety, open pit design, technical studies and geotechnical monitoring.
Johan Wesseloo Associate Professor Johan Wesseloo
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.
