Lord Porter Ultrafast Laser Spectroscopy Laboratory

An EPSRC Capital Equipment Award

At the Ultrafast Laser Spectroscopy Laboratory, 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​
  • photocatalysis
  • 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:
