Dr Marcus Yio is a Research Associate and the Laboratory Manager for the new Centre for Infrastructure Materials (CIM) in the Department of Civil and Environmental Engineering. 

Marcus holds a BEng in Civil Engineering (1st class honours) from the University of Sheffield, an MSc in General Structural Engineering (Distinction) and a PhD in Concrete Durability both from Imperial College London. His PhD research focused on the development of fluorescence laser scanning confocal microscopy for 3D and real-time imaging of cementitious materials. Following his PhD, he worked as a postdoctoral researcher at Heriot-Watt University, developing green building products from biopolymers and construction wastes.  

Marcus' main research interests lie in microscopic characterisation and durability of cementitious materials. He is currently responsible for setting up the CIM laboratories and developing an expertise in a range of advanced characterisation techniques including nanomechanical testing, thermal and sorption analyses, X-ray and vibrational spectroscopic methods, and their applications in civil engineering materials.
