Biophysical and Photophysical Chemistry

Our work develops new methods to characterise chemical and biological systems and their behaviour; explores the mechanisms of charge and energy transfer in molecules and material; and develops new analytical methodologies for the characterisation of molecular systems, biomolecules, and materials.

Major Themes

We are a dynamic, interdisciplinary group of people sharing passion for light-driven phenomena and (supra)molecular interactions at the interface of chemistry, physics and biology - collaborators welcome.

Ultra-fast processes, light matter interactions: charge and energy transfer in molecular systems and biomolecules, artificial photosynthesis and light-harvesting, photocatalysis, photodynamic therapy
Biophysical chemistry: single-molecule spectroscopy and microscopy, energy transfer in molecular systems, repurposing of natural systems for synthetic biology applications, self-assembling proteins and biological membranes, plant signalling
Surfaces and materials: plasmonics, surface spectroscopy, bionanotechnology, photonics
Applied spectroscopy: development of new analytical spectroscopic techniques and its applications, to study the metabolism of bacteria, and sensing of nutrients in soils.

Methods

Ultrafast laser spectroscopy: transient absorption and time-resolved infrared, 2D-IR, time-correlated single-photon counting, fluorescence upconversion spectroscopy.

Ultrasensitive techniques: single-molecule FRET, cavity ring-down spectroscopy, Raman spectroscopy, direct singlet oxygen detection.

Imaging techniques: Nanolithography, surface patterning, AFM, , Optical Coherence Tomography (OCT), FLIM and .

Protein engineering: rational design of self-assembling proteins and .
