Dr Dianne Sika-Paotonu is the Scientific Lead for the Rheumatic Fever and Penicillin Research Programme based in New Zealand and the Associate Dean (Pacific) at the University of Otago, Wellington. She is also a member of the Royal Society Te Apārangi Council and Health Research Council of New Zealand (HRC) Pacific Health Research Committee. She holds service and leadership responsibilities within the Pacific community and is an HRC Pacific Emerging Research Fellow, and recent recipient of the Sir Thomas Davis Te Patu Kite Rangi Ariki Health Research Fellowship from HRC. Dianne is also a member of the Takiala Pacific Leadership Network within the Health Sciences Division and Pacific Academic Staff Caucus Committee for the University of Otago. She sits on numerous local and University of Otago based Committees, in addition to International Governance Boards. She also functions as Chair and Convenor for Rheumatic Fever and Penicillin related Pacific Research Advisory Groups.

Selected major projects within the Rheumatic Fever related Penicillin Research portfolio that Dianne is currently leading include: Benzathine Penicillin G (BPG) Reformulation Preferences study for children and young people receiving secondary prophylaxis with BPG, the BPG Pharmacokinetics Study in New Zealand, the Reformulation Preferences of health professionals administering BPG for Rheumatic Fever prevention and the perspectives of Families with a Child/Young person receiving BPG injections for Rheumatic Fever prevention. These projects among other, are contributing to global collaborations and efforts to reformulate BPG for Rheumatic Fever prevention. This work is also extending into the Pacific Region in partnership with Pacific Researchers and Collaborators based in Oceania.

In the past, Dianne has worked at the Telethon Kids Institute (TKI) in Perth Western Australia where she remains an Honorary Research Associate and functioned as the Scientific Lead for the Penicillin Research work within the Group A Streptococcal Disease team based at the Wesfarmers Centre for Vaccines and Infectious Diseases. Dianne is also an Associate Investigator working on National and International projects such as “Towards a new long-acting penicillin formulation for rheumatic fever and rheumatic heart disease” and the National Science Challenge/Healthier Lives funded work “Circulating tumour DNA for better cancer management”, among many others. She is also a member of the New Zealand based research team investigating the Immunogenetics of Rheumatic Fever connected with the Genome Wide-Association Study International Consortium.

Dianne completed her PhD in Biomedical Science at Victoria University of Wellington specializing in Immunology based at the Malaghan Institute of Medical Research. While there Dianne was a member of the cancer vaccines team and undertook work that explored the modification of these vaccines to generate stronger immune responses against cancer. Her work showed that increased numbers of cancer-killing immune cells could be generated when synthetic compounds that mimic infected tissue were incorporated into the cancer vaccine preparation. Her work also highlighted the role of specific sub-populations of immune cells in generating these cancer killing immune responses. Dianne’s work overall aimed to improve of the potency of these cancer vaccines for the treatment of all cancers.

Dianne has received numerous awards for her PhD and other research work including the MacDiarmid New Zealand Young Scientist of the Year-Advancing Human Health & Wellbeing, Colmar Brunton Research Excellence Award, Australasian Society of Immunology BD Science Communication award, Asia Pacific Science Technology Studies Networks New Contributions to Science Technology & Innovation Award-Indigenous studies and the Australasian Society of Immunology Buck Memorial Award among others. Dianne was also recipient of the Royal Order Award the Most Illustrious Royal Order of Queen Salote Tupou III-Commander, awarded by the late King George Tupou V of Tonga in recognition of scientific achievement.

Dianne’s research interests include Immunology, Rheumatic Fever, Immunogenetics, Cancer and Pharmacology. Dianne is of Tongan descent and also has strong research interests in areas of health research relevant to Pacific populations living in New Zealand and in the Region. Dianne is an Honorary Research Associate with the Wesfarmers Centre for Vaccines & Infectious Diseases, Telethon Kids Institute, Perth, Western Australia and Victoria University of Wellington, and is an Affiliate with the Maurice Wilkins Centre for Molecular Biodiscovery, University of Auckland.
