Biography

Associate Professor. M. Maalej graduated from Colorado State University (BS 1989), the Massachusetts Institute of Technology (MS 1991), and the University of Michigan (PhD 1994). His PhD thesis was on the fracture resistance of engineered fibre cementitious composites and implications to structural behavior. His research interests include micromechanics-based design of fibre reinforced cementitious composites for infrastructural applications, fibre optic sensing for structural health monitoring, and application of FRP composites in the repair and strengthening of reinforced concrete structures.

A/P Maalej has been a staff member of the Department of Civil Engineering at the National University of Singapore (NUS) since August 1999. Prior to joining NUS, he worked for one year as a Research Fellow with the Advanced Civil Engineering Material Research Laboratory (ACE-MRL), Ann Arbor, Michigan, then joined the Canadian Network of Centres of Excellence on Intelligent Sensing for Innovative Structure (ISIS Canada) at the University of Toronto, Ontario, where he worked as a Research Engineer and a Postdoctoral Fellow until August 1999.

A/P Maalej has taught courses in concrete structures, cement and concrete composite materials, fracture and micromechanics of fibrous composites, and engineering mathematics. He has published over 35 technical papers covering topics such as micromechanical modeling and structural applications of short fiber reinforced cementitious composites, repair and strengthening of RC structures using externally-bonded FRP, and fibre optic sensing for structural health monitoring.

His current research projects include: Corrosion durability of functionally-graded concrete beams, fiber optic sensing for structural health monitoring, analysis and design of FRP-strengthened beams against debonding-type failures, and development of advanced materials and systems against close-in blast and penetration.
