Personal profile

Professional Information

He received a PhD from the Colorado School of Mines (CSM), USA. His main research interests are engineering rock mechanics; mechanized excavation and tunnelling, rock characteristics, testing & drilling. He has authored over 100 publications including peer-reviewed scientific journals, proceedings, industrial project reports and books. He is a recognized reviewer of many mining and geotechnical journals and also, Associate Editor of Tunnelling & Underground Space Technology. He is known for the studies of developing the Modified CSM Model for estimating Tunnel Boring Machine (TBM) performance, TBM performance prediction formulas, and also proposing rock brittleness index, test and classification. He joined the School of Mining and Geosciences at Nazarbayev University in June 2017.
