Our lab uses a multi-disciplinary approach to dissect the cellular interactions that underpin immune protection and disease. Our major interests are:

  • identifying factors that promote cell migration, and determining how these factors influence responses to acute and chronic infections, and successful vaccination.
  • determining the spatial niches where cell differentiation decisions occur during immune responses.
  • identifying novel mechanisms that resolve inflammation to limit immune pathology and promote life-long memory (particularly related to COVID-19).
  • transcriptionally dissecting the cellular conversations that mediate flexible immune responses and understanding how these are altered in asthma and lupus.
  • identifying pathways to target these processes as treatments for infectious and inflammatory diseases and to strategise vaccine design.

Systems we use include:

  • advanced imaging methods including whole 3D organ imaging and time-lapse imaging of cell location and migration decisions.
  • diverse infection models (viral, bacterial, helminth and fungal) and healthy and patient tissue samples to study flexible immune responses and animal models of inflammatory diseases.
  • development and analysis of reporter and conditional knockout models to identify how new factors regulate immune protection and memory responses.
  • global gene expression profiling of cells based on cellular interactions and positioning during immune responses.
