Dr. NS Raja Lab

Mission Statement

Develop an in-depth understanding of mechanisms and outcomes of altered redox signaling in disease to stratify clinical patients based on oxidative/reductive milieu which leads to ascertain innovative avenues for therapeutics. Main goal is to define the redox signals in cardiovascular pathophysiology and to develop potential therapeutic measures.

We are a firm believer of the fact that “Too much of anything is not good”, boosting the biological system with too many reductants may not be a healthy fix.

Our lab is committed to a diverse, impartial and inclusive environment that drives our professional growth as an individual and the team as a whole.
