Forskargrupp

Strukturell dynamik i vattenlösningar (SDAQS)

I gruppen är vi intresserade av att förstå vattnets roll i kemiska och biofysikaliska processer ur ett statistiskt fysikperspektiv. Vi studerar den strukturella dynamiken hos vattenlösningar, inklusive nanopartiklar, organiska molekyler och proteiner i underkylda och glasartade tillstånd.

Om mig

I am originally from Greece and my name is pronounced "Fee-vos", written also as "Fivos".

My group develops and utilizes X-ray scattering techniques to study the molecular structure and dynamics of aqueous solutions and supercooled liquids, as wells of proteins in crowded and cryogenic environments. Experiments involve Time-resolved X-Ray Diffraction and X-ray Photon Correlation Spectroscopy (XPCS) measurements at large X-ray facilities worldwide, such as X-ray storage rings and X-ray Free-Electron Lasers (XFELs).
