Among the Padma Awards recipients this year is Dr Kumarasamy Thangaraj, who is one of Bharat’s most respected genetic scientists. His pioneering work in population genetics and molecular biology has transformed the understanding of human origins in the Bharatiya subcontinent. A senior scientist at Hyderabad’s Centre for Cellular and Molecular Biology (CCMB), Thangaraj has spent more than three decades studying the genetic history, diversity, and health of Bharatiya populations. In recognition of his extraordinary contribution to science and engineering, the Bharatiya Government honoured him with the Padma Shri in 2026.
The Journey of Dr Kumarasamy Thangaraj
Thangaraj was born on 2 June 1963 in Tamil Nadu’s (TN) Cheyyur. He came from humble beginnings and developed a strong interest in biological sciences during his student years. He completed his B.Sc., M.Sc., and M.Phil. from the University of Madras before pursuing doctoral research in genetics. His academic journey eventually led him to CCMB in Hyderabad, one of Bharat’s premier biological research institutions. There, he emerged as a leading figure in human genetics and evolutionary biology.
One of Thangaraj’s most influential contributions has been his research into the origins of Bharatiya populations. Through advanced genomic studies, he helped establish that modern Bharatiya populations largely descend from two ancient ancestral groups: the Ancestral North Bharatiyas (ANI) and the Ancestral South Bharatiyas (ASI). This groundbreaking work reshaped historical and anthropological understanding of migration and population mixing in the Bharatiya subcontinent. His studies provided scientific evidence that Bharat’s population history is deeply complex, involving ancient migration, intermixing, and long periods of endogamy.
Another landmark achievement of Thangaraj’s career was his research on the indigenous tribes of the Andaman Islands. His team demonstrated that these tribal communities are among the earliest descendants of modern humans who migrated out of Africa nearly 65,000 years ago through the southern coastal migration route. This discovery attracted international attention because it provided crucial evidence about one of humanity’s earliest migrations. The findings significantly contributed to global discussions on human evolution and prehistoric migration patterns.
Other Important Contributions
Apart from population history, Thangaraj has made major contributions to medical genetics. He studied the impact of endogamy and consanguineous marriages on inherited diseases in Bharatiya communities. His research identified several population-specific genetic disorders and helped scientists understand how certain diseases become concentrated within isolated communities. These studies have important implications for public health, genetic counselling, and preventive healthcare in Bharat.
Thangaraj’s work has also extended into cardiovascular disease, mitochondrial disorders, infertility, and forensic genetics. One of his important discoveries involved a genetic variant linked to cardiomyopathy in Subcontinental populations. Such findings have helped bridge the gap between genetic research and practical healthcare applications. His studies continue to contribute to precision medicine and disease prevention strategies tailored to Bharatiya populations.
His Work During the COVID Pandemic
During the COVID-19 pandemic, Thangaraj contributed to genomic research exploring genetic susceptibility among Subcontinental populations. His involvement demonstrated how genetics can play a role in understanding disease vulnerability and public health responses. Throughout his career, he has consistently combined fundamental scientific curiosity with practical medical relevance.
Over the years, Thangaraj has authored hundreds of research papers published in prestigious international journals such as Nature, Science, Cell, and Nature Genetics. His publications are widely cited by researchers around the world, making him one of Bharat’s most influential scientists in genomics and evolutionary biology. He has also been elected Fellow of major scientific academies, including the Indian National Science Academy and the Indian Academy of Sciences.
In addition to his scientific achievements, Thangaraj is admired as a mentor who has inspired young Bharatiya researchers. He has repeatedly encouraged students to pursue careers in basic science and research, emphasizing that scientific progress is essential for national development. After receiving the Padma Shri, he remarked that the honour would motivate young Bharatiya scientists to continue contributing to research despite challenges.
Thangaraj’s recognition with the Padma Shri is a celebration of Bharat’s scientific research. His work has expanded global understanding of human evolution while addressing important medical and social issues within Bharat. By combining genetics, anthropology, and medicine, he has built a scientific legacy that connects the story of ancient human migration with modern healthcare challenges.
Today, Dr Kumarasamy Thangaraj stands as a symbol of scientific excellence in Bharat. His research has shown how genetics can illuminate humanity’s past while improving its future. Through dedication, innovation, and rigorous scholarship, he has earned a distinguished place among Bharat’s foremost scientists.
