  • Research Associate Professor
  • Faculty in Environmental and Occupational Health

My research interests primarily focuses on oxidative stress, peroxidase activity of hemoproteins, lipid peroxidation as death signals inducing ferroptotic cell death. I also interested in oxidative biodegradation of carbon nanomaterials.
