Research

Research Interests:

I was awarded my PhD in Physics in 1999 by Queen Mary and Westfield College for my work on transient photoconduction measurements on semiconducting Discotic Liquid Crystals in collaboration with the University of Leeds - Centre for Self-Organising Molecular Systems (SOMS). More specifically, I carried out Time of Flight (ToF) measurements on π bonded triphenylene systems, obtaining charge carrier mobilities and ranges and probing the trapping dynamics in different phases. This was followed by post-doctoral research at Queen Mary and Imperial College measuring charge transport in various organic systems, including binary discotic mixtures, polymer semiconductors and blends (e.g. donor-acceptor mixtures), including the electric field and temperature dependence of the transport. I was appointed lecturer at the Department of Physics at Queen Mary, University of London in 2003 and began an external industrial collaboration with Merck Chemicals Ltd on charge transport in reactive mesogens and polymeric semiconductors which enabled funding for my first two PhD students. I also undertook academic collaborations on Organic Magneto-Resistance (OMR – with Prof. W. P. Gillin, Physics, Queen Mary), on radio frequency (dielectric) applications of organic semiconductors (with Dr. R. S. Donnan and Dr. R. Dubrovka, Electrical Engineering, Queen Mary) and on the charge transport properties of blended and co-polymerised organic semiconductors (with Prof. N. Stingelin, Materials Science and Prof M. Heeney, Chemistry, Imperial College). The research on the microscopic mechanisms of OMR continues to date as does the work on tuneable dielectric applications of polymer semiconductors which was successfully funded by the Engineering and Physical Sciences research council in 2013. In 2008 I begun a collaboration with Prof. A. J. Drew and coworkers (Physics, Queen Mary) using muon spectroscopy methods to probe spin and charge dynamics in organic semiconductors. The research was complemented by transient conductivity work clarifying the charge injection mechanisms and identifying the dominant carriers operating in organic semiconductor based spin valves. In 2015 I begun a collaboration with Dr. A. J. Bevan (Particle Physics, Queen Mary) in applying polymer semiconductors and multi-component blends for radiation detection which has been funded industrially by AWE since 2016.  During my sabbatical in Sichuan University in 2016 I began a collaboration with Prof. K. Yu in the Institute of Atomic and Molecular Physics investigating the charge transfer between semiconducting polymer matrices and quantum dots and nanoparticles which allow us to identify the presence, nature and energetics of surface trap states.

I am a founding member of the Detector Development Group at the School of Physics and Astronomy, Queen Mary University of London.

Overall I have supervised and co-supervised 15 successful PhD candidates and I am currently supervising a further two as second supervisor. I have authored and co-authored 72 articles (excluding conference proceedings) to date (please see publications list)
