Fellowships and Visitors

We welcome enquiries to work with us from people seeking hosting on fellowship or visitor programmes. We have a significant base of ultrafast and single molecule spectroscopic equipment, and are happy to support proposals that can harness it for innovative work across the physical sciences. If you are interested in working with us then get in touch.

Current Openings

Post-Doctoral RA

We are seeking a post-doctoral research assistant to contribute to a newly funded EPSRC project entitled “Measuring Nanoscale Exciton Motion & Annihilation in Single Molecules with Photon Statistics”. This work will build on our recently published Nature Communications paper where we report a new technique to measure the spatial movement and interaction between excited states in light emitting molecules. We achieve this by recording the fingerprint of when individual photons are emitted as a function of time on single molecules. From this we can deduce how many excitons exist at any point in time, and thus how they move and annihilate with each other.

In this project you will utilise, enhance, and expand these methods to explore how excitons in organic semiconductors behave and how loss mechanisms such as singlet-singlet annihilation can be reduced in materials relevant to organic light emitting diodes, solar cells and organic laser devices. Skills in single molecule spectroscopy, microscopy, ultrafast spectroscopy, organic semiconductor photophysics and time-resolved optical spectroscopy are desirable. Applicants should have a keen interest in developing new techniques and pursuing novel high-impact science.

The post is full time with funding for 18 months. For more information and to apply online: click here

PhD Position

We have an open PhD position in advanced single molecule spectroscopy in the Hedley Lab, to start in October 2021.

This PhD will focus on themes alongside exciting new funded grants that we have recently secured researching the nanoscale motion of energy and quantum coherences of excited states in organic semiconductor materials. Using a microscope to measure light emitted from individual molecules one at a time, you will contribute to a growing team that aims to understand how excited states form, move, and interact in molecules used in organic light emitting diodes, photovoltaics, and organic lasers. This will be achieved by exploiting the photon statistics – how photons are distributed in time – of light emission from molecules to extract valuable new information, enhancing the development of new techniques made in our recent Nature Communications paper.

This PhD will require frequent work with lasers, optical setups, photophysical measurements, sample preparation, microscopy measurements and extensive data analysis.

A 1st or 2:1 or equivalent undergraduate degree in physics, chemical physics, chemistry, or related discipline is required. This position is open to UK nationals or EU students with UK settled status. A 2-page C.V. and cover letter should be sent to along with following the university online application process here (please do both).
