Dr Nikki Moreland
BSc Waik., PhD Auck.
Dr Nikki Moreland is a Senior Lecturer in Immunology and joined the faculty as a member of staff in 2016. Nikki obtained her PhD from the University of Auckland and was previously a research fellow in the School of Biological Sciences, Auckland and Duke-NUS Graduate Medical School, Singapore. She has also held positions in the British pharmaceutical industry bringing a translational element to her research.

Dr. Moreland’s laboratory studies the mechanisms that drive antibody specificity using a combination of protein biochemistry and molecular biology. The laboratory seeks to better understand how a functional antibody repertoire can protect against infection, yet dysregulation of the immune system produces autoantibodies that can attack the body’s own tissues.
The major research focus of the laboratory is rheumatic fever, an autoimmune disease that can develop after an untreated Group A Streptococcus infection. Globally, Group A Streptococcus is placed in the ‘top 10’ infectious causes of human death. The rates of rheumatic fever in Māori and Pacific children in New Zealand are amongst the highest in the world, and the disease pathology is poorly understood.
The laboratory is profiling the antibody repertoires of patients with rheumatic fever using a variety of technologies including high content protein arrays and antibody phage display. Mapping the antibody specificities in rheumatic fever will improve understanding of the disease and contribute to the development of better diagnostics.
The group is also involved in efforts to develop new vaccines for Group A Streptococcus. Biochemical and biophysical techniques are used to elucidate the molecular mechanisms by which antibodies recognise potential vaccine antigens to inform vaccine design.
