Senior Lecturer at the School of Civil and Environmental Engineering

Dr Ailar Hajimohammadi received her Ph.D. on sustainable cementitious materials from the University of Melbourne in 2011. She worked in the international technology company AspenTech for four years (2011-2015) where she gained experience in industry consultation and training. She did three years of postdoctoral research at the Infrastructure Engineering Department, University of Melbourne (2015-2018) before joining the faculty at the University of New South Wales. Ailar’ s research examines the chemistry of materials to develop innovative construction elements with attractive properties. She is also investigating waste management and resource recovering strategies towards circular economy in civil and construction projects.
