Zhixin Liu received his PhD degree in Information Engineering from the Chinese University of Hong Kong, in 2012. After a short start-up experience, he joined the Optoelectronics Research Centre (ORC) at the University of Southampton in 2013 and became a Senior Research Fellow in 2015. In 2016, he joined the optical networks group at the Department of Electronics and Electrical Engineering at UCL and became an associate professor in 2021. Dr Liu is a senior member of both IEEE and Optica (former OSA). 

His research areas are optical signal processing and its applications in communication systems and scientific equipment. He has pioneered new techniques for high precision data conversion and low-latency data communications that have led to several world's first demonstrations. Dr Liu has co-authored more than 100 papers in international peer-reviewed journals and conferences, with several high-profile papers in Nature Electronics, Nature Communications, 8 invited papers in IEEE/OSA J. Lightwave Technol. and 7 post-deadline as well as top-ranked papers in leading optical communication conferences (OFC and ECOC). 

Dr Liu regularly gives invited talks in leading international conferences and serves in technical programme committees in leading international conferences inc. CLEO-PR, OECC and ACP. He also holds two patents, with one licenced to a leading industrial manufacturer. Dr Liu has been PI on over 10 grants from Industry and Research Councils, totalling over £1.7M. He is Co-I on the £6.1m EPSRC Programme grant TRANSNET.

His research interests include: 
•    High performance frequency comb
•    Coherent signal processing 
•    Low-latency, low-power consumption transceivers for data centre interconnects 
•    Integrated photonic circuits for communication systems
