Job title: Research Associate in Tracking energy transfer in (bio)molecular photonic breadboards in the strong coupling regime

Do you enjoy exciting, cross-disciplinary and cutting-edge research? We invite applications for a postdoctoral position, tenable for up to two years in the first instance, as part of a £7.25 M collaborative project funded by EPSRC and led by Prof G. J. Leggett. You will join a team of nine other postdoctoral researchers and five PhD students across the Universities of Sheffield, Bristol and Exeter with lead investigators in Chemistry (Prof S. P. Armes FRS, Prof J. Weinstein and Prof N. H. Williams (Sheffield)), Biology (Prof C. N. Hunter FRS (Sheffield) and Prof D. N. Woolfson (Bristol)), Physics (Dr J. Clark, (Sheffield) and Prof W. L. Barnes (Exeter)) and the Faculty of Medicine, Dentistry and Health (Prof D. W. Lambert).


The aim of our five-year programme is to develop a new, modular approach for the creation of photonic materials, inspired by biological photosynthetic membranes. We call this approach 'molecular photonic breadboards': minimal units - synthetic antenna complexes - are designed from scratch to organise molecular components precisely in space. These building blocks are assembled to form nanostructured films. We will exploit the exciting new physics of strong light-matter coupling, and seek to control energy transfer pathways from the nm to the cm scale. Our goal is to lay the foundations for a revolution in the design of molecular photonic materials.


Your role will be to delve into the detailed photophysics of strong-coupled molecular photonic breadboard materials. Working with the entire team, your role will be to characterise energy flow within the manifold of excitonic, polaritonic and plexcitonic states in the weak and strong coupling regimes using a range of time-resolved spectroscopic techniques. In addition, you will map spatial energy transfer in films of plexcitonic materials. You can view more details about the post and our project by visiting:
