Hossein Masoumi graduated from Tehran University, Iran with Bachelor of Science degree in Mining Engineering in 2007 and completed the level of Master of Mining Engineering, major in Mine Management and Mine Geomechanics in 2009 at the School of Mining Engineering, UNSW. He received his PhD degree in Geotechnical Engineering from the School of Civil and Environmental Engineering, UNSW in 2013. He had been an Associate Lecturer at the School of Mining Engineering from 2012 till 2016. He promoted to Lecturer in 2016 at UNSW and then moved to Monash University in Jan 2018 as a Senior Lecturer. Currently he is a head of resources group and leader of resources Engineering at Monash University.

His main research lies in the field of rock mechanics with particular interest in size/scale and shape effects on intact rock. Constitutive modelling of intact rock exhibiting size/scale dependent behaviour under uniaxial and triaxial conditions is the key aspect of his research interest.
