Appointed Cardiff University Research Fellow 2015.

Dr Roldan's research is aimed at understanding the dynamism of surface processes that underlie phenomena such as catalysis and corrosion. His group employs a range of computational tools to model physical and chemical properties of these systems regarding the experimental synthetic and working conditions. The use of micro-kinetic models allows them to approach specific conditions including the optimization of the catalyst structure and working conditions improving yields, selectivity of the catalyst as well as controlling sintering effects.
