Professor Martin Cryan has worked in the fields of electromagnetic modelling, device and circuit fabrication for 40 years. He worked for GEC Marconi Instruments and then for Quasar Microwave from 1986-1990. He did his PhD at Bath University and post-doctoral research at the University of Birmingham, the University of Perugia in Italy and from 2000 at the University of Bristol. He became a lecturer at Bristol in 2002 and a Professor of Applied Electromagnetics and Photonics in 2012. He is interested in metasurfaces, metamaterials, plasmonics, photonic crystals, nanophotonics and radio frequency-photonics applications. In 2017 he co-founded a Bristol-based start-up FluoretiQ Ltd which is developing low-cost biosensors and is hoping to commercialise light-controlled radio-frequency switch technology which he is currently developing.
