Dr Hajirasouliha obtained his PhD in 2006 with a distinction grade from Sharif University of Technology in Iran, which is one of the leading technological universities in the Middle East. His research led to the development of an advanced optimisation theory in the field of performance-based design of structures that was awarded the “Tavakoli Prize” for conducting original research at Sharif University of Technology and “Distinguished Young Researcher Award” by the Iranian Earthquake Engineering Association. In 2008, he was awarded a prestigious Marie Curie individual fellowship (IIF) at The University of Sheffield on optimum strengthening of deficient RC buildings using FRP composites. From 2010 to 2012, Dr Hajirasouliha was a Lecturer in Structural Engineering at the University of Nottingham, where he was convener of “Advanced Concrete Structures” and “Earthquake Engineering and Structural Dynamics” modules. In 2012, Dr Hajirasouliha was appointed Lecturer in Structural Engineering in the Department of Civil and Structural Engineering at The University of Sheffield.

Dr Hajirasouliha’s main research interests are Earthquake Engineering, Structural Dynamics, Performance-Based Design, Optimisation, Structural Strengthening, and Soil-Structure Interaction. He is currently a member the department's  Concrete and Earthquake Engineering research group.
