Paul Campbell graduated with a Honours in Biochemistry in 1983 and again in Medicine in

1986 from the University of Glasgow. He was awarded a D. Phil in Molecular Haematology from the University of Oxford in 1991. He spent several years in Registrar posts in Adelaide, first in Clinical Chemistry at the Institute of Medical and Veterinary Science and then in Rheumatology, Immunology and Allergy at Flinders Medical Centre. He was concurrently a NH&MRC Australian Postdoctoral Research Fellow in Immunology, lecturing in Immunology at The Flinders University of South Australia. During this time, he also trained for Fellowship of the Royal College of Pathologists of Australasia, which he was awarded in 1997. He then spent  a short time as Senior Registrar in Paediatric Haematology at the Adelaide Women's and Children's Hospital before accepting a position as a Senior Immunologist for the UK Medical Research Council at a remote field station in The Gambia in West Africa. This work was curtailed early because of his wife's first pregnancy and they returned to Australia for the birth of their first child.

Dr. Campbell then moved from Adelaide to the Mid-North Coast and has worked as a General Practitioner in Bellingen for the last six years. He is now opening The Allergy Centre with the intention of providing an evidence-based, state-of the-art, specialist Immunology and Allergy service to the region. He lives near Coffs Harbour with his wife and three children.
