Professor Charlie Li
Professor of Rock Mechanics
The Norwegian University of Science and Technology, Norway
Professor Li is a professor at Norwegian University of Science and Technology (NTNU), Norway. His expertise is in stability analyses of underground spaces and ground control. His research interests are specifically on the performance of rockbolts and ground support in high rock stress conditions. He published the book of Rockbolting – Principles and Applications in 2017. He invented the D-Bolt for rockburst control in deep mines.
Charlie is a member of the Norwegian Academy of Technological Sciences (NTVA). He was the ISRM vice president for Europe 2015 to 2019.
Professor Erling Nordlund
Chaired Professor, PhD
Luleå University of Technology, Sweden
Erling is the chair and professor in rock mechanics and rock engineering at the Division of Mining and Geotechnical Engineering, Luleå University of Technology, Luleå, Sweden. He has more than 30 years’ experience in research, and the supervision and teaching of rock mechanics. Erling’s research has covered the fundamental studies of deformation and failure processes in rock with experimental and theoretical methods, rock mechanics applied to civil engineering and mining problems, both static and dynamic numerical problems, and rock support–rock mass interaction for deep mining conditions.
Professor Yves Potvin
Professor for Mining Geomechanics
Australian Centre for Geomechanics
Yves joined the Australian Centre for Geomechanics at The University of Western Australia in 1998 and was centre director, 2000-2019. Professor Potvin has published more than 100 articles and is the editor/co-editor of 14 conference proceedings and books. He has 40 years of experience in rock mechanics and mine design and has previously held managerial positions at Mount Isa Mines, the Noranda Technology Centre and worked as a mining engineer at Noranda Mines, Gaspe Division. Yves undertakes numerous collaborative industry-focussed research projects and is presently involved with the ACG’s Ground Support Systems Optimisation Project, and the Stope Reconciliation and Optimisation Project.

Professor Pekka Särkkä
Emeritus Professor of Rock Engineering
Helsinki University of Technology, Finland
Principal Ground Control Engineer
Glencore Canada Corporation, Canada
Brad has over 20 years’ experience in deep hard rock mining having worked in the in the South Africa Gold Fields, northern New Brunswick and since 2003 Glencores’ Sudbury Nickel Operations. He has authored and co-authored numerous papers on rockburst resistant ground support, mining induced seismology, and deep mining strategies. His current role oversees the ground control programs for the Nickel Rim South (structurally complex nickel/copper deposit), Fraser Copper (extensively mined narrow vein copper deposit), and Fraser Morgan (blasthole nickel mine) operations as well as the Onaping Depth Project (2.3 to 2.7 km deep Nickel resource).
Dr Jonny Sjöberg
General Manager & Chairperson
Itasca Consultants AB, Sweden
Jonny Sjöberg is a rock mechanics engineer with experience in operations, research, and consulting. He has worked for several mining and consulting companies on projects dealing with underground and surface mining rock mechanics, civil engineering tunnelling, and rock stress measurements. Currently, he is the general manager of the Itasca Office in Sweden. He is also appointed adjunct professor in rock mechanics and rock engineering at the Luleå University of Technology.

Divisional Director of Geomechanics
Codelco Chile, Chile
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 director
