We are interested in all aspects of light-matter interaction in condensed phase.
Examples of some of our research directions include:
- charge and energy transport in molecules and materials
- ultrafast electronic, vibronic, and structural dynamics
- organic optoelectronics
- solar cells
- artificial photosynthesis
- photosynthetic, photoprotective and other natural and synthetic pigment-protein complexes
- organic polaritonics
- materials for energy
- photoswitchable materials and devices
- synthetic biology
- biological imaging
- light-induced therapies in healthcare
- thin films
We are members of the EPSRC Grand Challenges Networks:
We are integrated into multiple University of Sheffield initiatives:
Laboratory Capabilities at a glance
Spectra Physics ~40 fs 10 KHz amplifier, a 5 KHz ps amplifier, and a 1 KHz, 100 fs amplifier.
- 10 KHz, ~100fs transient absorption spectroscopy with detection from ca. 360 nm to 1600 nm (HELIOS). Tuneable excitation across UV/visible range.
- Time-resolved mid-IR spectroscopy (TRIR).
- 2D-IR – PhaseTech pulse shaper, and a picosecond pump.
- Femtosecond broadband fluorescence upconversion. Collaboration with Professor Niko Ernsting, Humboldt University of Berlin.
- Transient absorption with <50 fs resolution.
- Angle-dependent time-resolved photoluminescence.
The Opening Meeting on 14 March 2018 was attended by ~150 laser enthusiasts, with >100 from outside Sheffield

1st Annual Symposium
28 June 2019
Lecture Theatre 1, Dainton Building, S3 7HF
We aim to bring together UK researchers from across the disciplines to discuss what's new in the time-resolved world across Physics, Chemistry, Biology, Engineering, and Medicine.
Most of the talks will be from PhD students and postdocs with plenty of time allocated for a poster session if you'd like to bring a poster.
