Design of Adaptive Structures
Active Structural Control
EngD MRes MSc MEng (Hons)
I am a scientist and engineer specialized in computational structural mechanics, structural optimization and form-finding. My expertise includes computer-aided design, algorithmic modelling and generative design. I am currently a postdoctoral scientist at Swiss Federal Institute of Technology (EPFL). I previously worked as a postdoctoral scientist at University College London and as the Head of computational design & research at London based practice Expedition Engineering.
I developed new integrated design and control methods for smart structures that counteract the effect of loads actively through sensing and actuation. The Adaptive Structures produced by this method have a low environmental impact, they can be extremely slender and at the same time deflections can be controlled within tights limits. This is particularly beneficial to stiffness governed designs including high-rise buildings, self-supporting roof systems and bridges. These methods have been successfully tested experimentally validating key assumptions and numerical predictions. My work on adaptive structures has been exhibited internationally.
I also developed an interactive physics engine software to aid teaching in structural mechanics and structural design. The model, a vector-form finite element method which combines dynamic relaxation with the co-rotational formulation, can simulate structures with non-linear geometric behavior and perform shape optimization in real-time. The software, called PushMePullMe, has been adopted worldwide.
I hold an Engineering Doctorate (EngD) from University College London. Previously, I was awarded with distinction an MSc in Computing and Design at the School of Architecture, Computing and Civil Engineering of University of East London in 2009 and an MSc in Emergent Technologies at the Architectural Association (London, UK) in 2008. I graduated in mechanical engineering MEng (Hons) at Federico II University (Naples, Italy) in 2006.
