Christopher Leung is a practicing research engineer, he holds an engineering doctorate from UCL (University College London) for original contributions to building technology from his work on passively activated thermal actuators for operating movable building facades. He holds an academic post as an Associate Professor at UCL. His research interests are in the challenges of expressing design intent for manufacturing, in particular, applied to novel technology for the built environment. He is a contributor to UCL's "Advanced meteorological sensing network", focussed on studying net radiation and the potential for passive radiant cooling in urban and sub-urban roofscapes. He is an active member on the UK national standards committee TPR (Technical Product Realisation) contributing to existing and new standards for technical documentation using the GPS (Geometrical Product Specification) language.
