PhD positions in ultrafast laser spectroscopy at the University of Sheffield, UK

PhD positions are available at the University of Sheffield, UK, to work on an exciting cross-disciplinary project, Molecular Photonics Breadboards,

PhD 1: Mapping Energy Transfer in Time and Space.

Lead Supervisor: Dr Jenny Clark, Department of Physics and Astronomy,

In this project you will use a newly developed microscopy technique, stroboSCAT3 to track excitonic energy transfer in photosynthetic membranes and synthetic photonic systems developed within the wider project. This exciting technique will allow you to map exciton transport with picosecond time resolution using light intensities relevant to solar energy harvesting for the first time. You will work closely with a postdoctoral researcher to develop and refine the microscope in Sheffield and to directly track energy transfer.

PhD2: Ultrafast Electron Transfer in Plexcitonic Systems

Lead Supervisor: Prof Julia Weinstein, Department of Chemistry,

The ability to control photo-processes by external perturbation could bring a new way to manipulate photonic materials. Coupling between electronic and vibrational degrees of freedom (vibronic coupling) on the ultrafast timescale is the key factor in the photophysics of molecular excited states. However, manipulation of the coupled states is difficult! In this project, you will use strong light-matter coupling to plasmon modes to affect and potentially control vibronic coupling, and hence the outcome of light-driven reactions. This work builds on our previous development of the IR-control approach to manipulate excited state reactions.[3] A particular focus of your project will be on electron and energy transfer pathways in molecules and materials, that might be important in applications including photocatalysis and solar energy capture.
