Research Interests:

Currently I am working on Nrf2 and INrf2 signalling with following areas:

  1. To study the role of Nrf2 and INrf2 (Keap1) in the modulation of cell signalling in cancer.
  2. To study the Nrf2/INrf2 signalling in the tissue specific conditional knockout mouse model.
  3. To study the role of Nrf2/INrf2 in cancer prevention.
