We have a large and vibrant community of doctoral students researching a broad range of topics in electronic and electrical engineering. Our graduates are in high demand, going on to careers in industry, academic research, and permanent academic positions at top institutions. Many of our graduates now hold senior positions in the industry. Thanks to the breadth of research we carry out in the department, we offer doctorates across a wide range of topics in electrical engineering, from nanotechnology and novel materials, to circuits and systems, radar, communications, photonics and optical networks and large scale networks. We collaborate widely, both with other departments in UCL, and internationally with leading research groups around the world. Research areas: Communications and information systems: telecommunication networks and services; wireless communications; IP networks; sensor networks; information security and retrieval. Electronic materials and devices: optical materials and electronic devices; quantum nanoelectronics; diamond electronics; laser processing; resistive switching. Optical networks: optoelectronic devices and systems; large scale optical networks; dense WDM optically routed networks; optical packet networks; high speed optical systems. Photonics: ultrafast photonic devices; wireless over fibre devices and systems; photonic generation of THz signals; advanced liquid crystal devices; uncooled and coherent wavelength division multiplex technology. Many of our recent PhD graduates have taken up positions as postdoctoral researchers at leading universities, whilst others continue their research careers in industry. A significant number use the PhD as a stepping stone to careers in other sectors, including management consultancy and finance. Several have started up their own businesses and become successful entrepreneurs.
