Vice-Chancellor's Senior Fellow at Northumbria University

Academic Visitor in the Centre for Material Physics

Member of Hatfield College Advisory Board



Funded PhD studentship starting October 2020 (with Dr Aidan Hindmarch)

It is my pleasure to be a co-supervisor on a funded studentship (at UK/EU level) as part of the ReNU Renewable Energy Northeast Universities Center for Doctoral Training: Spin dynamics in multilayer organic photovoltaics and organic light emitting diode films. The closing date for applications is 31st January 2020.


I'm Marc and I am currently a Vice-Chancellor's Senior Fellow at Northumbria University (and Junior Research Fellow at Hatfield College, Durham University) leading a group researching the photophysical and functional properties of organic semiconductors. I am also an academic visitor in the group of Prof. Andy Monkman continuing our joint work and projects on novel materials that exhibit thermally activated delayed fluorescence. Before my visiting position, I worked in the OEM group Durham from March 2015 as a research associate on two different projects (PHEBE and HyperOLED).

I'm originally from Stockton-on-Tees and as such I am local to the area. I first came to Durham as an undergraduate student in 2007 studying for my MPhys at Grey College. This included a fourth year project under the supervision of Prof. Andy Monkman.

After graduating in 2011 I went up to Cambridge to undertake my PhD in Physics at Clare College under the supervision of Prof. Neil Greenham. The title of my thesis was 'Magnetic field effects on the triplet states in organic semiconductor devices'.

Alongside my membership of Hatfield College SCR I am also a member of the SCRs at University College and Grey College.
