About

Background

Dr Weiping Wu is the George Daniels Lecturer in the Electrical and Electronic Department, City University London.

His recent research focus is on novel sensing devices, such as optical sensors, chemical sensors and gas sensors. His research interests also include novel materials, thin films, nano structures for electronic devices (transistors, light-emitting diodes and memories), energy harvest (solar cells), and energy storage (super capacitors and batteries). He also did simulation and experimental research in the field of high frequency electronics, microwave, Terahertz (THz) and nano photonics with novel materials and structures.

He joint the University of Cambridge as a Research Associate in 2010. He worked on graphene and 2D materials for optoelectronics, in the Electrical Engineering Divison in the Engineering Department at Cambridge University from 2010-2013. He was an early member in the Cambridge Graphene Centre, worked on EPSRC and EU Graphene Flagship projects.

In 2013, he was appointed as a Research Fellow in the Optoelectronics Research Centre (ORC), University of Southampton where he worked on lasers, optical fibres, nano photonics and metamaterials.

Dr Wu is a worldwide known researcher on functional materials, semiconductors and photonics. He has discovered several novel materials, he also designed and demonstrated several novel devices such as novel transistors, photo-detectors and memories. He has published more than 50 papers with a total citation over 2000, and an h-index of 25. He contributed an invited book chapter for the United Nations Educational, Scientific and Cultural Organization (UNESCO).
