Sir Mark Edward Welland, FRS, FREng (born 18 October 1955) is a British physicist who is a professor of nanotechnology at the University of Cambridge and head of the Nanoscience Centre.
He has been a fellow of St John's College, Cambridge, since 1986 and started his career in nanotechnology at IBM Research, where he was part of the team that developed one of the first scanning tunnelling microscopes.
Currently at the Nanoscience Centre at the University of Cambridge researches into a number of aspects of nanotechnology ranging from sensors for medical applications to understanding and controlling the properties of nanoscale structures and devices.
[20] His nomination for the Royal Society reads:Mark Welland is a world leader in nanotechnology and scanned probe microscopy.
His achievements combine the development of new experimental tools for nanoscale characterisation with the modelling of nano-scale properties, and an interdisciplinary approach to practical applications.
