Personal profile

Research interests

My research concerns multiscale modelling of organic and perovskite electronic devices. This research is described on my personal webpages http://people.bath.ac.uk/pysabw/ and http://people.bath.ac.uk/pysabw/abwmod.html where links to my EU and EPSRC projects are provided along with links to videos I have made illustrating my research.

I coordinate two EU H2020 projects:

I am Bath team leader for the Centre of Excellence EoCoE (Energy Oriented Centre of Excellence, 2015-2018). Saiful Islam and Rob Scheichl are also funded by EoCoE.

I am Academic Director for the Centre for Doctoral Training in New and Sustainable PV (CDT-PV) funded by the EPSRC, that has 7 universities and is lead by Ken Durose at the University of Liverpool.

I have been appointed to the REF2021 subpanel 9 in Physics.
