Dr Yunuen Montelongo obtained his PhD in 2015 at the University of Cambridge in the Centre of Advanced Photonics and Electronics. Then, he continued with his postdoctoral training in the Chemistry Department at the Imperial College London. Currently he is a Research Fellow in the Department of Engineering Science and Wolfson College at the University of Oxford. The research work of Dr Montelongo focuses in the development of reconfigurable materials for photonic devices. His research includes theoretical aspect of the light-matter interaction and experimental demonstrations involving nanostructured materials. The applications of reconfigurable materials include sensors, metamaterials, holographic displays, data storage, tuneable lasers among many others.
