Liv Hornekær is Professor of Materials Science at Aarhus University and center leader of InterCat. She heads the experimental activities under InterCat at Århus University.

Her group specializes in experimental surface astrochemistry. By combining state-of-the-art experimental surface science methods, the group can trace surface reactions on the atomic scale at ultra-low pressures and temperatures. Under InterCat these capabilities will be harnessed to investigate the (photo-)catalytic activity of realistic interstellar dust grain analogues for the formation of the molecular building blocks of life.
