Leigh Canham is Professor of Nanomaterials for Biomedicine & Photonics and has over 30 years experience conducting R&D on widely different aspects of silicon technology.

He specialises in nanostructuring the semiconductor to tune its properties for potential uses that range from optoelectronics to medicine to consumer care products.

He enjoys multidisciplinary research and spent over 15 years in industry after co-founding a medical device company before taking a position in the Nanoscale Physics Group in February 2017.

Qualifications

  • PhD in Solid State Physics 1983
  • BSc Physics 1979

Biography

Leigh Canham was trained as a solid state physicist at University College London (BSc 1979) and Kings College London (PhD 1983). His entire R&D career in academia, government labs and industry has been focussed on the semiconductor silicon. Two key personal discoveries- that nanoscale silicon can emit light efficiently (1990) and be medically biodegradable (1995) have had significant academic and commercial impact.

Since 1999 he has held an Honorary Professorship at the University of Birmingham for his work on luminescent silicon. In 2011 Leigh was a shortlisted finalist for the European Inventor of the Year award from the European Patent Office for his work on biodegradable silicon. Two recent awards are that of Thomson Reuter Citation Laureate (2012) and the Materials Innovation Medial of the Federation of European materials Societies (2015).

Leigh regularly gives lectures internationally on nanoscience and technology, entrepreneurship and nanoscale silicon R&D.

Research
