Hossein Masoumi, Senior Lecturer in the Department of Civil Engineering, in the Faculty of Engineering at Monash University, in Australia. He received his PhD from the University of New South Wales. His research focuses on rock mechanics, particularly the size/scale and shape effects on intact rock, constitutive modelling of intact rock exhibiting size/scale behaviors under different test conditions, shaly-sandstone micro-scale characterization, and non-persistent jointed rock characterization. He has had over ten projects supported by the Australian Coal Association Research Program (ACARP) and the Mining Education Australia (MEA) Collaborative Research Project. He has published over 30 papers.
