Introduction

Dr Stephen Morris is a Royal Society University Research Fellow at the Cambridge University Engineering Department. I am based in the Centre of Molecular Materials for Photonics and Electronics located at the CAPE building on the West Cambridge Site.

My other roles include:

Programme manager for the COSMOS Project (Coherent Optical Sources based upon Micromolecular Ordered Structures). This research project is focussed on developing compact, tuneable laser devices using organic structures. I have been the programme manager since 2008 and led the proposal for the Technology Translation award in 2010. More details on the research project can be found at the dedicated website:  http://www-g.eng.cam.ac.uk/cosmos/.

I am also the student facilitator for the Photonic Systems Centre for Doctoral Training, which is a joint training programme between the University of Cambridge and University College London. More details can be found at: http://www.photonicsystems.org.

 

Teaching

Stephen is a Fellow and Director of Studies in Physics at St Catharine’s College and a supervisor for Part I physics. A link to the College website can be found here: http://www.caths.cam.ac.uk/

Details on the Liquid Crystal Displays lectures that I give as part of the 4th Year Engineering Course (4B20: Display Systems) can be found here:
