Research interests

We have been using the pKZ1 transgenic mouse chromosomal inversion assay to study the mutagenic effect of very low doses of DNA damaging agents. We demonstrated that very low doses of radiation can protect from endogenous chromosomal inversions suggesting that low doses of radiation can protect from chromosomal damage. Our current research focuses on understanding the mechanism of low dose radiation induced protection from mutation and cancer. We have a number of active projects including:

  • The temporal response for chromosomal inversions after low dose radiation exposure
  • The effect of known chemical radioprotectors on chromosomal inversion in association with low dose radiation.
  • The effect of low dose radiation on DNA methylation levels
  • The role of radiation induced bystander effects after low dose radiation in vivo
  • Intercellular induced apoptosis as a possible mechanism for low dose radiation induced protection from cancer
  • Effect of low dose radiation on prostate cancer progression in a mouse tumour model
