Surfaces and interfaces define the properties of materials. Understanding processes occurring at surfaces and interfaces allow us to develop advanced devices such as flat panel displays, solar cells, rechargeable batteries, automobile catalysts, gas or biosensors. All these devices are fruit of the intense research involving study of the structural and electronic properties of surfaces as well as their interaction with molecules. With the help of surface science tools we can now investigate materials at the molecular scale and come closer to the understanding how to tune properties of surfaces and molecules for specific applications.

The main subject of my research is devoted to study adsorption of molecules (inorganic, organic and biomolecules) on solid surfaces with particular interest in the mechanism by which molecules adsorb and form self-assembly on the surface. We study adsorption of proteins on metal electrodes in a liquid environment with the aim to control protein adsorption and function through modification of the surface and protein molecule. In a second line of research we try to gain spectroscopic insight into the specific interactions of lipids and proteins in biological model membranes.
