I'm interested in developing methods that might make high-fidelity MDO a practical tool for designing the next generation of highly flexible aircraft. For example, in my MSc thesis and the corresponding conference paper, I expanded the Lab's MACH framework to enable the use of geometrically nonlinear finite element models which are critical for accurately modelling the aeroelastic behaviour of very flexible wings.
More recently I have been working on a framework for including geometrically nonlinear flutter constraints in high fidelity aerostructural optimization.
