Profile: I study the deformation of composite materials using computer modelling and simulation.
Dr Connie Qian
Senior Lecturer in Composites
I grew up in China and came to study in the UK in 2005. I graduated with a 1st class BEng in Mechanical Engineering in 2009 and then a PhD in Mechanical Engineering in 2014, both from the University of Nottingham. My PhD was on RVE modelling and structural optimisation for discontinuous carbon fibre composites.

After completing my PhD, I stayed at the University of Nottingham as a Research Fellow from 2014-2018, during which I developed process simulation models for composites sheet forming, injection moulding, and thermoplastic overmoulding.

In 2018, I joined WMG at the University of Warwick as a Research Fellow and was later appointed as Assistant Professor in 2021, where I developed process simulation models for high-pressure RTM, double-diaphragm forming and compression moulding. My research vision started to shape during my time at WMG, as I became strongly interested in integrated process-property-performance simulation for compression moulded discontinuous fibre composites and hybrid architecture composites.

I joined the University of Sheffield as a Senior Lecturer in Composites in 2024 and in my spare time, I play the piano and the violin, and foster cats for the Blue Cross.

Research interests

My research focuses on process-structure-property-performance modelling for fibre reinforced composites. I am particularly renowned for my research in high-volume manufacturing of discontinuous fibre composites, and have led several funded research projects in this area, notably an Innovation Fellowship funded by the EPSRC Future Composites Manufacturing Hub. I also have strong experience in applied research and have delivered large CR&D projects with industrial partners across the whole composites supply chain. I'm most active in the automotive domain, and have worked with some of the world's most-respected OEMs such as Jaguar Land Rover, Ford and Aston Martin.

My research interests are:

Composites manufacturing process simulation
Multi-scale modelling for composites
Structural simulation and structural optimisation
High-volume composites manufacturing processes
