Biography

I'm Marc and I am currently an Assistant Professor 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.
