[8] As a senior registrar at GOSH, he attempted to introduce a new procedure using the biopsy needle but was unsuccessful due to the opposition from the paediatricians and pathologists, who believed it could only be done under general anaesthetic.

[8] However, Alan Moncrieff encouraged him to research the pathology of Liver biopsy's and managed to convince the medical staff that it could be successful.

[4] In 1960, White was seconded to the Makerere University College medical school in Mulago Hospital in Kampala, Uganda for two years.

[4] Together they decided to conduct a clinicopathological study of children[12] with nephrotic syndrome in the region southeast and southwest of the River Thames.

[3] The work started the embryo of a renal unit at Guy's Hospital that eventually led to the development of a world-class paediatric nephrology centre that was run by both Cameron and Chisholm S Ogg.

[4] White's study attracted the attention of Henry Barnett, a paediatrician who worked in the Albert Einstein College of Medicine in the New York.

[13] Barnett along with Chester Edelmann and Ira Greifer created the International Study of Kidney Disease in Children in 1966 in the United States.

[13] White along with Renée Habib in France and Jacob Churg in the USA were the lead assessors and reported on the pathology of the biopsies.

[4] In 1965, Douglas Hubble, who at the time was chairman of the British Paediatric Association[14] believed there was a need to develop several paediatric specialities in Birmingham and invited White to work at the Birmingham Children's Hospital[7] White was appointed to the position of senior lecturer, employed with the express purpose of developing a children's renal unit.

[15] Seeking to create a comprehensive renal centre in Birmingham hospital in the same manner as he did in Guys, he recruited a collaborator Elizabeth Ward, who would later found the British Kidney Patient Association in 1975.
