Research and interest

Currently, my research consists of looking at the interplay between surface roughness and change in contact mechanics of interfaces from the nano to the macro-scale. My main research project is on the growth of anti-wear tribofilms. This project reflects on my scientific convictions as it aims to improve the performances and reduce the cost of green energy production.
