Dr Caroline Gwendolyn Walker

2012 PhD Biomedical Science (Liggins Institute)


I am a molecular biologist with research interests in the molecular mechanisms regulating health and disease. I completed my PhD at the University of Auckland in 2012 under the supervision of Professors Murray Mitchell and Russell Snell and Dr John Roche. Currently I am a Senior Research Fellow at the University of Auckland Centre for Longitudinal Research, where I am part of the Growing Up in New Zealand Research team.

Research | Current

My research focusses on the molecular mechanisms regulating health and disease. In particular I am interested in the genetic and epigenetic regulation of health-related phenotypes. Previous research has focussed on advancing our knowledge of the molecular mechanisms regulating fertility and the immune response by utilising high throughput sequencing technologies to quantify genetic variation, DNA methylation, gene expression and microbial diversity associated with fertility and the immune response. Currently, I am part of the research team for New Zealands contemporary longitudinal study Growing Up in New Zealand (http://www.growingup.co.nz) based at the Centre for Longitudinal Research - He Ara ki Mua (https://www.fmhs.auckland.ac.nz/en/soph/centre-for-longitudinal-research.html).
