'I particularly value access that I have gained to Fashion Design students within Tokyo's Bunka Fashion College, as well as leading universities in Antwerp, Berlin, Beijing, Shanghai, New York, Paris and Tunis.'

Hartnett's photographic work has been internationally published in a wide range of books produced by Laurence King, Harper Collins plus Thames & Hudson.

Curator Jon Swinstead of Subculture Archives recently stated, 'Peter Paul Hartnett is a visionary creative, with a keen eye to life's fine details. His resourceful and minimal manner sets his work in photography, prose and everything he sets out to do, apart from the crowd.'

A little known aspect of Peter Paul Hartnett's career trajectory is that in the late 80s, throughout the 90s and into the 00s, Hartnett headed two Special Educational Needs departments in secondary mainstream schools in Tower Hamlets, London.

He has also worked with young people with SLD (severe learning difficulties), EBD concerns (emotional and behavioural difficulties) in specialised units, as well as young people with PMLD (profound multiple learning difficulties) and those with complex medical needs, within therapeutic settings.
