Biography

Robert Hadfield is Professor of Photonics in the James Watt School of Engineering at the University of Glasgow.  He served as Head of the Division of Electronic and Nanoscale Engineering from August 2014 to July 2018.  He is a co-investigator of QUANTIC, the UK Quantum Technology hub in imaging and QComm, the UK Quantum Technology hub in quantum communications.  He is a founder member of the University of Glasgow Centre for Quantum Technology and serves on the Executive Committee of the James Watt Nanofabrication Centre.  He is based in the University of Glasgow Advanced Research Centre under the Quantum and Nano theme.

He completed his PhD at the University of Cambridge, UK in 2003.  He was a postdoctoral guest researcher at the US National Institute of Standards and Technology in Boulder, Colorado from 2003 to 2006.  He returned to the UK in 2007 as a Royal Society University Research Fellow at Heriot-Watt University and was promoted to Reader in Physics in 2009.  

He was awarded the 2012 J&E Hall Gold Medal of the Institute of Refrigeration, the 2013 Brian Pippard Prize of the Institute of Physics Superconductivity Group and the 2019 James Joule Medal of the Institute of Physics.  He was elected a Fellow of the Institute of Physics in 2010, a Fellow of the Institution of Engineering and Technology in 2015, a Fellow of the Optical Society of Amercia in 2016 and a Fellow of the Royal Society of Edinburgh in 2019.  He is a Senior Member of IEEE and SPIE.  He has served on the editoral boards of the Journals Superconductor Science and Technology (IoP), Optics Express (OSA) and Royal Society Open Science (Royal Society of London).    He joined the editorial board of Optica (OSA) from April 2019.  He is editor of a major title in the Springer Quantum Science and Technology Series, Superconducting Devices in Quantum Optics, published in spring 2016.  He was Guest Professor at the Royal Insitute of Technology (KTH), Stockholm, Sweden in August 2018 through the Wallenberg Centre for Quantum Technology.  He held a European Reserch Council Consolidator Grant from 2015-2019 and a Royal Society Leverhulme Trust Research Fellowship in 2018-19.  He was co-chair of the European Conference on Applied Superconductivity, EUCAS 2019, at the Scottish Event Campus, SEC, in Glasgow in September 2019.  He will co-chair the Single Photon Workshop SPW2024 in Edinburgh in autumn 2024.

Applications

Applications for research positions at all levels are welcomed: undergraduate internships, PhD research, postdoctoral fellowships and scientific visitors. 

Please contact Professor Hadfield <robert.hadfield@glasgow.ac.uk>

Full scholarships for UK candidates are awarded competitively through the James Watt School of Engineering PhD Application Call closing 31st January 2024.  A further round is expected in May/June 2024.  Interested candidates should contact Prof Hadfield well in advance for support in submitting a full application.  We work closely with a range of companies, and industrial sponsorship can be arranged for suitable candidates.
