My research focuses on environmental physiology, specifically how insects adapt to changes in
their environment and coordinate that at a molecular level during embryonic development. Aligned to
this I am also interested in how epigenetics can control gene expression through regulating transcription
and translation in response to external environmental signals, especially during development. The aim of
my research is to develop an understanding of the cellular response to environmental cues and how that
affects normal development. I have an additional interest in global change biology and am involved in a
longitudinal study to assess the impact of land use on bacterial fauna by determining the loss of
biodiversity in bacterial species using metagenomics. I am also passionate about science communication
and teaching and have active research interests in these areas.

Research Interest

  • Evolution of insect development
  • Transcription and translation control in growth and differentiation
  • Genome structure organization and its role in gene expression
  • The impact of land use on bacterial biodiversity
