Enrico Gnecco is a Professor of Physics. He received his Ph.D. from the University of Genova and worked as a junior researcher at the University of Basel and as a senior researcher at IMDEA Nano­science, Madrid. He was a Professor of Materials Science at the University of Jena and since 2021 is a professor of physics at the Jagiellonian University in Krakow, Poland, and visiting professor at our chair. He is inter­natio­nally recog­nized for his work in nano­tribo­logy and related topics. His current research activities focus on sliding friction in different environmental conditions, scanning probe microscopy-based manipulation, contact mechanics, and abrasive wear processes on the nanoscale. On this subject, Prof. Gnecco has co-authored several articles in major journals including Science, Nature Materials, PNAS, and Nano Letters, and two books. He also edited and authored three books on friction and related processes upon invi­tation by Springer, World Scientific Publi­shing and Cam­bridge University Press, and co-edited two thematic series on Nano­tribo­logy and Nano­mani­pulation and environ­mental nano­techno­logy in the Beilstein Journal of Nano­techno­logy. Prof. Gnecco has co-organized several inter­national work­shops and serves as a reviewer for many scientific journals and granting agen­cies in Switzer­land, Germany, Israel, and the USA. In his spare time, he also used to play the piano and write short pieces of music.
