Research Interests

I would like to train myself in the advanced composite characterisation techniques that include experimental as well as numerical analyses. Working as an ESR in the ICONIC project will help me achieve this goal as the training provided is coherent with my research interests. ICONIC also boasts the collaboration with industry beneficiaries such as Short Brothers plc and Centro Ricerche Fiat S.C.p.A., and research centres like Swerea SICOMP AB, which are trying best develop composites for real-world applications. In the future, I would like to work at a research institute or company to employ my knowledge and expertise for the sustainable development of society.
