RMIT University, Melbourne, Australia

Position: Postgraduate Student


  • - Project title: Characterisation of multifunctional composites exhibiting mechanical and thermal management capabilities
  • - Microencapsulated Phase Change Materials (micro-PCMs) were integrated into the Fibre Reinforced Plastic (FRP) composites to develop a material system that exhibits structural and thermal management capabilities. To achieve such a materials system, the influence of embedded micro-PCMs on the host material was investigated.

Research Interests

I believe a primary goal of an engineer is to push the boundaries of technology and improve the quality of people’s lives. Since I was seeking a doctoral course which provides me with the opportunity to expand my knowledge in composites, I was interested in the ESR position within the ICONIC project due to its benefits such as collaboration opportunities. Furthermore, it is based on the crashworthiness of composite transportation structure where I can directly impact people’s daily lives. Also, this opportunity will enable me to fulfil my life-long goal of receiving engineering training to positively contribute to world-class research in composite materials at both the national and international level. This is the reason why I wanted to work as an ESR at the Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR).
