Biography

Anding Zhu received the Ph.D. degree in electronic engineering from University College Dublin (UCD) in 2004. He has been working in UCD since 2005, first as a Post-doc, then a Lecturer, an Associate Professor and now he is a Professor in the School of Electrical and Electronic Engineering. His research interests are in the area of nonlinear modelling and characterisation of RF circuits and systems with a particular emphasis on digital linearisation of RF power amplifiers for wireless communications. He has published over 100 peer-reviewed papers and received research funding from various sources including awards from Science Foundation Ireland (SFI), European Space Agency (ESA), Enterprise Ireland (EI) and industry donations.

Prof. Zhu collaborates with many universities and international companies. Between 2004 and 2007, he was actively involved the EU FP6 Network of Excellence TARGET. He was appointed as a Guest Research Fellow in the Wireless Circuits and Systems Group at University of Aveiro, Portugal in 2006 and worked as a Visiting Scholar in the High Speed Device Group at University of California at San Diego (UCSD) in 2007. Prof. Zhu was undertaking a sabbatical leave working as a Visiting Assistant Professor in the Department of Electrical Engineering at Stanford University from January to June 2013. Prof. Zhu is currently with the RF & Microwave Research Group at UCD and he is the Director of the IoE2 Lab, a multi-disciplinary research laboratory particularly focusing on developing enabling technologies and making scientific breakthroughs for next generation Internet of Things (IoT) and future (5G) communication networks. Prof. Zhu is a Funded Investigator in the SFI Research Centre for Future Networks and Communications - CONNECT  where he is particularly working on physical layer network-aware intelligent radio access nodes in collaboration with Xilinx, Analog Devices, MA-COM and Synopsys.
