Rajesh Ramasamy is an Associate Professor and Principal Investigator of the Stem Cell & Immunomodulation Research Group at the Faculty of Medicine and Health Sciences (FMHS), Universiti Putra Malaysia (UPM). He trained at Universiti Kebangsaan Malaysia (BSc Biomedical Science / Immunology, 1997–2000) before completing his PhD and DIC in stem cell transplantation and immunology at Imperial College London (2002–2006) under internationally recognised mentors. He subsequently joined UPM in 2006, where he has since built one of Malaysia's leading programmes in mesenchymal stem cell biology and applied immunomodulation research.
His research addresses two broad axes: the immunoregulatory properties of mesenchymal stem cells (MSCs) — including their effects on T cells, monocytes, macrophages, neutrophils, and microglia — and the regenerative potential of phytochemical compounds such as Moringa oleifera and Cassia auriculata in immunosuppressed and metabolic disease models. He holds a Diploma in Siddha Medicine Science (AIAMA, Tamil Nadu, 2011–2012), reflecting a long-standing engagement with traditional South Asian healing systems, and has delivered invited talks at the Central Council for Research in Siddha (Chennai, 2019) and at the International Conference on Tamil Siddhar Tradition (Universiti Malaya, 2026).
