Dr Raj Das is an Assiciate Professor in the Aerospace and Aviation department of RMIT University, Australia and an honorary academic in the University of Auckland, New Zealand. He is a principal investigator of the ‘Sir Lawrence Wackett Aerospace Research Centre’ of RMIT University. He is an adjunct academic of the University of Quebec, Canada. He is the Deputy Chair of the ‘National Committee on Applied Mechanics’ of Engineers Australia.

Dr Das has published more than 200 papers in international journals and conferences. Dr Das has a PhD from Monash University, Australia in Structural Optimisation and Failure Analysis. Dr Das has previously worked in the University of Auckland, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), and the University of Manchester.

Dr Das has research capabilities in advanced materials, such as metamaterials, auxetic materials, architected materials, composite materials, topology and shape optimisation for materials and structural designs, computational modelling, fracture mechanics, dynamic fracture, damage tolerance based optimisation, numerical modelling and multi-scale analysis using finite element and mesh-less methods, impact behaviour and failure analysis of metals, ceramic and composite materials. Dr Das has been extensively promoting applied mechanics, computational mechanics and fracture mechanics research within the Australasian region. He was the chair of four major scientific conferences recently held Australia and New Zealand. He has served on the scientific committees of more than 80 international conferences. Dr Das is on the editorial board and review panel of several journals and funding agencies.

Dr Das has been granted several national and international awards and fellowships, including the ‘Jim & Hazel D. Lord Emerging Faculty Fellowship’, ‘Research Excellence Award’, and ‘AUEA Emerging Researcher Award’ by the University of Auckland. He has received the ‘CONICYT award’ from the Government of Chile, ‘Certificate of Merit Award’ from the International Association of Engineers, Hong Kong, ‘UQAC Visiting Fellowship’ from the University of Quebec, Canada, and ‘Visiting Researcher Fellowship’ from the University of Cape Town, South Africa.
