Research Interests

During my school days, the prevalence of Mechanical Engineering in the real world excited and attracted me to pursue Bachelor and Master studies in Mechanical Engineering. Although I was equally fascinated by solid and fluid streams in Mechanical Engineering, my experience during graduation training through coursework on mechanics of materials, linear and non-linear finite element method, and challenging application-driven industrial assignments at General Motors guided my choice to pursue a research career in this research area of my ESR project. With a lot of emphasis on light weighting and design of crashworthy structures across industries, characterisation of composite materials has been a research area with high potential and impact. Joining of such materials adds on to the complexity of the research. The applied nature of my ESR position and networking opportunities in ICONIC, to understand the challenges in realising a sub-system scale development, drove my interest to this ICONIC research project.

Outreach

Promotion of ICONIC and the EU Horizon 2020 MSCA programme at the DRaF symposium

 

During my secondment at Centro Ricerche Fiat S.C.p.A. in Pomigliano d’Arco (Italy), I attended the International Symposium on Dynamic Response and Failure of Composite Materials (DRaF) on 12-15th June 2018 in Ischia. During the interesting symposium, I interacted with the attendees and presenters, and promoted my ICONIC research work and the EU Horizon 2020 MSCA programme.
