Reasearch Interests
I work in the field of organic semiconductors and am interested in the fundamental optical and electronic properties of these systems. The aim of my research is to develop new frameworks and ideas to enable the creation of truly molecular optoelectronic devices. I started my PhD working on organic light-emitting diodes (LEDs). The bulk of my work focused on the development of a new class of materials based on star-shaped molecules, called dendrimers. I performed a wide range of measurements and calculations on these systems, which also led to the filing of a number of patents.

More recently, I have developed a number of techniques for the characterisation of defects in conjugated polymers using ultrafast fluorescence spectroscopy and gated electroluminescence spectroscopy. Further interests have been in molecular thermometry and semiconductor microcavities. I am now working on using single molecule spectroscopy to gain a microscopic understanding of charge generation and recombination and excitation energy transfer processes as well as assessing the possibility of quantum electrodynamical control of individual excitations. My main focus is on excitonic effects in conjugated polymers, triplet spectroscopy of organic semiconductors and the photophysics of novel inorganic colloidal semiconductor nanostructures.
