Research interests

Dr Juliet Pullar obtained her PhD at the University of Otago, Christchurch under the supervision of Professors' Margreet Vissers and Christine Winterbourn. Her work was focused on thiol biochemistry, uncovering targets of the neutrophil-derived oxidant hypochlorous acid in endothelial cells.

Dr Pullar continued onto a NZ Science and Technology Postdoctoral Fellowship in the Centre for Free Radical Research with Professor Mark Hampton studying the redox regulation of apoptosis. She has expertise in cell biology, cell culture, flow cytometry, ELISA, HPLC, spectrophotometry, microscopy, neutrophil function, fertility analysis, electrophoresis and western blotting.

More recently Dr Pullar has been working with Professor Margreet Vissers investigating the biological functions of vitamin C. This has allowed her to gain further expertise in carrying out human studies. Her current projects include investigating the use of red blood cell ascorbate as an indicator of vitamin C status, understanding the pharmacokinetics of vitamin C in the skin, and the role of vitamin C in the healing of chronic wounds.

She completed a Diploma in Public Health in 2010. Dr Pullar teaches part of the BBiomedSc(Hons) programme, has co-supervised three summer students and is currently co-supervising one PhD student and one Masters student.
