Christofer "Chris" Toumazou, CEng (Greek: Χριστόφορος Τουμάζου, born 5 July 1961) is a British Cypriot electronic engineer.

He is perhaps best known for inventing a fast and portable means of genome sequencing, following his 13-year-old son's diagnosis with end stage kidney failure through a rare genetic mutation.

[2] For his inventions in semiconductor-based genetic testing he won the Gabor Medal of the Royal Society (2013) and European Inventor Award (2014).

[4] Born to Greek-Cypriot parents in Cheltenham, Toumazou trained to become an electrician, inspired by an English uncle who was an electrical engineer.

[7] His own specialism is in the field of personalised healthcare, providing worn or implantable devices for early diagnosis, and detection of disease.
