I started my PhD, within the theory group of the Max Planck Institute for Polymer research, in
July 2016. My focus is currently on development of the Kinetic Monte Carlo algorithm, for electronic processes
I obtained my Master of Science degree, in Molecular science, at the Friedrich-Alexander-University of Erlangen-Nuernberg, in 2015. My Master thesis was carried out at the Max Planck Institute for the science of light, in Erlangen. The focus of the thesis was a computational investigation of a
composite nanostructured semiconductor, for the use as a water splitting photocatalyst.
I received my Bachelor of Science (Honours) in chemistry, from the University of Glasgow in 2011.
My Bachelor thesis was concentrated within the area of computational chemistry, namely the
comparison of canonical and local electron correlation descriptions, when considering small

Unicoloured phosphor-sensitised fluorescence (UPSF) is a dual emitting concept proposed for improving efficiencies and operational lifetimes of blue organic light emitting diodes (OLEDs). To overcome the limitations of the individual emitters it uses a phosphorescent donor to sensitise a fluorescent acceptor. To quantify the potential of the concept we develop a multiscale model of a UPSF OLED. We start from atomistic morphologies parameterise the rates of all processes on the available experimental data and solve the respective master equation with the help of the kinetic Monte Carlo algorithm. Our simulations show that the energy transfer between donor molecules is essential to reproduce the results of the time-resolved photoluminescence experiment. We then expand the scope of experiment by studying the effect of the acceptor concentration as well as Förster and (parasitic) Dexter energy transfer from the donor to acceptor on the characteristics of the UPSF OLED. Our study shows that an appropriate material design can further improve efficiency by more than 30\% and at the same time achieve radiative decay times below 0.02 µs thus significantly extending OLED operational lifetime.
