Helen Vethakan Raj

Dr Helen Vethakan Raj is a Teaching Professor at the University of Southampton, contributing to both academic instruction and research in toxicology and environmental health. Her work focuses on cellular responses to environmental pollutants, particularly the effects of brake wear particles, vanadium exposure, and particulate matter on alveolar epithelial cells.

Her research interests include understanding mechanisms of toxicity in respiratory systems, stress response pathways, and the impact of nanomaterials on cellular homeostasis. Recent studies emphasize differential toxicity comparisons between automotive particulate sources, such as brake wear versus diesel exhaust.

Publications highlight collaborations on topics like copper-enriched brake particles disrupting alveolar homeostasis and the role of MTF-1/Nrf2 pathways in stress signaling. These contributions advance knowledge in environmental toxicology and respiratory health.

No scientific awards or current PhD advisees are listed. Her work is affiliated with interdisciplinary teams at the University of Southampton, though specific lab or team affiliations are not detailed in the provided information.
