Research Interests

Dr Velayutham’s research interest has been focusing on understanding the role of free radicals, reactive oxygen species, and NO in cardiovascular biology/diseases. We apply electron paramagnetic resonance (EPR) spectroscopy and imaging techniques and various biophysical modalities to measure and map redox status in in vitro and in vivo biological systems. Our research interests also include the development of chemo-preventive drugs/biomolecules and understanding the mechanisms of these drugs/biomolecules in the application to cardiovascular diseases and organ transplantation.
