About me

In our group we utilize coherent X-ray scattering techniques to study the molecular structure and dynamics of supercooled liquids and glassy materials, as well as aqueous solutions in biophysics. Experiments involve Coherent X-Ray Diffraction and X-ray Photon Correlation Spectroscopy (XPCS) measurements at large X-ray facilities worldwide, such as X-ray synchrotrons and free-electron lasers.

See here the group members.
