Senior Researcher, NanotechnologyNRC Cambridge
Professional Activities
Paul Beecher is a senior researcher at the NRC laboratory in Cambridge, UK. There he is a member of the Enabling Morph team. Much of this activity comprises collaborative work with researchers in the Electrical Engineering Division (part of the Engineering Department, University of Cambridge) on new technologies for large area sensing surfaces. Prior to that, he was a postdoctoral researcher in the EDM group at Cambridge University Engineering Department.
Paul’s technical background is in novel electronic materials. His postdoctoral work was directed towards the investigation of materials for fabrication of flexible and transparent electronics, primarily employing techniques compatible with industrial-scale production: ink-jet printing of composite organic based devices, incorporating nanoscale materials such as carbon nanotubes and silicon nanowires, and sputtering of ionic amorphous oxide semiconductors (e.g. zinc oxide) to fabricate transparent devices. His postgraduate work was devoted to probing the electrical interfacing of nanoscale devices, especially those consisting of small assemblies of metal nanocrystals. Paul has a degree in Electrical Engineering and a Ph.D. in Microelectronics (from University College Cork, Ireland).

Personal Information
Away from work, Paul’s main interest is in quizzing. He is a former winner of a university team quiz show on Irish television representing University College Cork, and was a finalist in Only Connect, a BBC quiz show, while representing Cambridge University Quiz Society. His other interests include football, golf, running, cinema, reading, and amateur dramatics, in which he has experience at acting, directing, and producing. He is also a member of the Cambridge Union.
