    Biography

    Dr Hajimohammadi is a postdoctoral research fellow in the Department of Infrastructure engineering working in an industrially linked research group led by Prof Priyan Mendis and A/Prof Tuan Ngo. She received her PhD from The University of Melbourne. Her PhD focused on the “reaction mechanisms in solid reactant-based geopolymer systems” . Dr Hajimohammadi collaborated extensively with leading experts in this field, including Prof Jannie van Deventer and Prof John Provis. Dr Hajimohammadi won a prestigious Japanese award of Cheiron to participate in the 2008 International Synchrotron School at the facility Spring8 in Japan. She conducted highly successful experiments at large-scale synchrotron facilities in the Australian Synchrotron and is well-versed in the process of designing and carrying out high-impact research at major facilities. After completing her PhD, Dr Hajimohammadi worked at AspenTech (a US-based global company) as a consultant. In this capacity, she worked closely with large construction companies and engineering consultancy companies such as Uhde Shedden, WorleyParsons and Clough within Australia and New Zealand. She was trained in writing professional services proposals as well as management and budgeting of the projects. Dr Hajimohammadi’s successful contribution to industry is demonstrated by the global Award of Excellence that she received in February 2013.Since June 2015, Dr Hajimohammadi has taken up a postdoctoral position at the University of Melbourne working on an ARC-Linkage Project, where she collaborated with the industry partner to bridge the gap between experimental research and practical applications of geopolymers. During her postdoctoral position, Dr Hajimohammadi collaborated with industry experts and academic professionals in the department. Dr Hajimohammadi has contributed to a successful grant application awarded by Sustainability Victoria which focused on the development of novel, sustainable construction materials. Throughout her postdoctoral position, Dr Hajimohammadi has continued to investigate the complex nanostructure of geopolymer precursors, and has dedicated part of her research endeavours to the methodological and technical development which benefits not only geopolymer research but also materials science in general. Dr Hajimohammadi has attained a senior membership of RILEM (international union of experts in construction materials and structures) where she can disseminate knowledge and collect feedback through major international Technical Committees (TCs).
