Professor Charlie Ironside is a professor in the Department of Physics and Astronomy at Curtin University (Western Australia). He received his PhD from Heriot-Watt University (Edinburgh) and in 1998 was appointed Professor of Quantum Electronics at the University of Glasgow. He has over 30 years of experience in semiconductor optoelectronics research and in particular, microfabrication of photonic components. He is a Fellow of the IET, a Fellow of the IOP, and senior member of IEEE. Along with hundreds of papers, he has co-authored five patents. Bruno Romeira received a PhD degree (summa cum laude) in physics and the European PhD degree from the University of Algarve, Faro, Portugal, jointly with the University of Glasgow, UK, and the University of Seville, Spain, in 2012. His research cuts across several disciplines in applied physics and engineering, which include semiconductor physics, quantum nanoelectronics, low-dimensional nanostructures, and nanophotonic and neuromorphic devices. José Figueiredo received a BSc in physics (optics and electronics) and a MSc in optoelectronics and lasers from the Universidade do Porto, Portugal, in 1991 and 1995. He did his PhD work at the University of Glasgow, Scotland, on the optoelectronic properties of resonant tunnelling diodes, enrolled in a joint programme between the Universidade do Porto and the University of Glasgow. Then he moved to the Universidade do Algarve, Portugal. He joined the Physics Department of the Faculty of Sciences of the University of Lisbon in 2017. He is member of the CENTRA research unit (tecnico.ulisboa), Portuguese Society of Optics and Photonics, European Microwave Association, Optical Society of America, and IEEE Photonics Society.
