Dr. Rajesh Gandhirajan is a professor and biomedical researcher and academic specializing in redox biology, translational medicine, and the therapeutic applications of Cold Atmospheric Plasma (CAP). He is affiliated with Sri Ramachandra Institute of Higher Education and Research, where his work integrates molecular biology, cancer therapeutics, infection biology, and regenerative medicine. His research focuses on understanding how reactive oxygen and nitrogen species (RONS) modulate cellular signalling, microbial persistence, and tumor vulnerability.
Dr. Gandhirajan has contributed extensively to advancing CAP-based biomedical applications, particularly in oncology, wound healing, and antimicrobial strategies against drug-resistant pathogens. His ongoing translational research includes studies on chronic diabetic foot ulcer infections, biofilm eradication, and ex vivo testing of experimental therapeutics on patient-derived tumor tissues. He employs multidisciplinary approaches combining molecular profiling, transcriptomics, metabolic assays, and advanced imaging techniques to bridge fundamental biology with clinical relevance.
An active scientific speaker and collaborator, Dr. Gandhirajan has delivered invited lectures at national and international conferences, including presentations on the emerging opportunities and challenges of plasma medicine and redox therapeutics. His research interests extend to leukemia biology, oxidative stress-mediated signalling, and the development of novel therapeutic platforms targeting resistant cancers and infectious diseases. His laboratory is funded by national agencies such as Indian Council of Medical Research (ICMR), Department of Biotechnology (DBT) and Board of Research in Nuclear Sciences (BRNS)
Beyond research, he is deeply engaged in student-centric teaching, mentoring, and academic innovation, with a strong commitment to training future scientists in rigorous experimental thinking and translational biomedical research.
