Samir is leading structural concrete research at the School of Engineering, University of Birmingham. His research focuses on resilience and sustainability of existing and new infrastructure assets. His research interests range from fundamental material behaviour to overall system response. Specific topics include strengthening and repair of existing structures, low impact concrete, nonlinear finite element modelling and structural health monitoring. Moreover, Samir is actively contributing to other areas of Structural Engineering research including, but not limited to, steel and aluminium structures.

Samir works closely with leading research groups in the UK and beyond. He has led and/or successfully delivered research projects funded by EPSRC, Horizon 2020, the UK construction industry, the British Council and overseas funders.
