Biography

I currently hold an appointment as a Senior Research Fellow with the Maurice Wilkins Centre, a Centre for Research Excellence. My primary research interest brings together my strong expertise in multicolour flow cytometry, cellular immunology and mesenchymal stromal cell biology to try and better understand immune/stromal cell interactions in health and disease. I am also an experienced flow cytometrist, which has developed from my role directing the Flow Cytometry Shared Resource Laboratory at the School of Biological Sciences. My research career initially focussed on human immunology (T cells, antigen presenting cells, APCs) specialising in developing advanced multicolour flow cytometry panels to characterise and monitor immune cells in both blood and digested tissues. I am currently utilising these expertise in a number of consulting roles - developing complex panels for immune monitoring in clinical trials. More recently, my primary research lies in dissecting stromal cell heterogeneity in various human tissues.

Current Research:

I am currently developing innovative and integrative technologies to investigate stromal cell heterogeneity, to try and better understand the diverse cellular populations involved in health and disease. Specifically, I am interested in reconciling the confusion, discrepancies and controversies that surround “mesenchymal stem cell” research in adipose tissue. These studies will have the potential to contribute significantly to the field of mesenchymal research by characterising the heterogeneity of human adipose stromal cells. A comprehensive overview of the different cell populations and importantly, their function, is still lacking. There is currently a huge push to define the stromal vascular fraction of adipose tissue due to their widespread use in unapproved therapies. The use of advanced flow cytometric techniques (26 colour flow cytometry panels) as well as single cell approaches (scRNAseq/CITEseq), will likely accelerate our current understanding of the cellular composition of adipose tissue. 

 

Multicolour Flow Cytometry

As well as a Reseacrh Fellow, I am also director of Auckland Cytometry, the flow cytometry core facility for the Faculty of Science. Much of my work is centred on developing multicolour flow cytometry panels to assess the phenotypic heterogeneity of digested tissues. We have recently acquired next generation spectral cytometers and are currently running up to 26 colours simultaneously.

The two main areas that I work in are human immunology and mesenchymal stem/stromal cells.

 

Human Immunology

  • Characterisation of antigen presenting cells in human blood and tissues (lymph nodes)
  • Characterisation of myeloid cell populations in human blood
  • Immune profiling 
  • T cell culture/cloning

Mesenchymal Stem/Stromal cells

  • Characterisation of adipose tissue progenitor cells: in search of the beige/brite fat precursor cells 
  • Characterisation of mesenchymal and vascular cell populations in human skin (dermis)
  • Characterisation of mesenchymal cell populations in the human lymph node
