Welcome to the Nonlinear Chemical Imaging Group
Our group focusses on characterising the heterogeneity in chemical structure at interfaces using ultrafast nonlinear microscopy techniques, with the aim to connect these lateral microscopic variations to the macroscopic physical properties.

New Group Member: Rafał Białek
Feb 2026
We would like to welcome Dr Rafał Białek who has just joined as a postdoc in our group. His project will be on the development and application of phase-resolved SFG microscopy under liquids for biological applications.
New Paper in Faraday Discussions
Jan 2026
Our work using azimuthal-scanning phase-resolved SFG microscopy to elucidate the in-plane packing structure in molecular films has been published in Faraday Discussions. We look forward to presenting our latest work in April and discussing it with our peers at the ‘Vibrations at Interfaces’ meeting. You can read more here.
Group Trip to the Xmas Market
Dec 2025
To celebrate a successful year, the group enjoyed a nice Glühwein at the Christmas markets in Berlin. Merry Xmas everyone and happy new year!
New Group Member: Tao Yang
Jul 2025
We would like to welcome Dr Tao Yang who has just joined as a postdoc in our group. He will be working on the development of a phase-resolved SHG microscope and its application to 2D excitonic materials and thin molecular films.
New Archive Paper: Multipole Contributions in SFG
May 2025
We have a new archive paper led by the group of Roland Netz wherein we disentangle the electric and magnetic multipole contributions to the SFG spectra from the air-water interface. This work shows the importance of including electric quadrupole and magnetic dipole contributions for the correct assignment of the spectral line-shapes. You can read more here.
