Ziyao Zhao earned a BSc in Materials Science and Engineering in 2022, and an MSc at Imperial College London, focusing on developing a polystyrene microfluidic mixer for 3D bio-printing. Her research experience spans metal materials, secondary battery simulations, and biotesting. Ziyao is working on designing acoustic metamaterials integrated with ultrasound transducers for broadband excitation and reception of guided waves, utilizing additive manufacturing. The aim is to create a metamaterial matching layer with a gradient acoustic impedance to transfer energy across a wide frequency range efficiently.
