The identified areas of expertise within CNH are defined here to help guide interested parties to the appropriate area and the key academics working therein.

The groups are not exhaustive and significantly overlap and interlink with each other, and many researchers work naturally across multiple groups.  

The clinical expertise available through the College of Medicine and neighbouring ABM Health Board support each area as required, and the key clinical staff are listed in this group, although the CNH is able to draw on additional expertise as required.
