The 2024 list of the world’s top 2% scientists, curated by Stanford University in collaboration with Elsevier’s data repository, has once again highlighted the impressive contributions of Indian researchers, with a special focus on Tamil Nadu. Of the 5,351 Indian scientists included in the prestigious global ranking, 537 are from Tamil Nadu universities, accounting for over 10% of the Indian contingent. This recognition underscores the growing prominence of Tamil Nadu’s research institutions in contributing to global scientific advancements.
Stanford University’s annual ranking identifies thetop 2% of scientists in the world across various disciplines. The 2024 edition, released on September 16, is based on research publications updated through 2023. The database is comprehensive, covering 22 scientific fields and 174 subfields, ensuring a broad representation of scientific endeavors. This year’s list comprises 2,23,152 scientists globally, with India contributing 5,351 names, a significant rise from 4,635 in 2023.
The inclusion of 537 scientists from Tamil Nadu showcases the state’s academic strength and the quality of its research output. Tamil Nadu’s representation in this list is a testament to the rigorous academic culture fostered within its universities and research institutions.
Among Tamil Nadu’s top institutions contributing to this achievement are the Indian Institute of Technology-Madras (IIT-M), Vellore Institute of Technology (VIT), SRM Institute of Science and Technology, and Anna University, among others. Notably, IIT-M leads the way with 62 scientists making the cut, followed closely by VIT with 59 scientists. SRM Institute of Science and Technology boasts 35 scientists on the list, and Saveetha School of Engineering and Saveetha Dental College and Hospitals have 26 and 25 scientists, respectively.
Other key contributors include Bharathiyar University, the National Institute of Technology, Tiruchirappalli (NIT-T), and Saveetha Institute of Medical and Technical Sciences, each with 19 scientists featured. Anna University, one of the oldest and most prestigious technical universities in the state, has 18 scientists included in the list, reaffirming its standing as a hub for research and innovation in South India.
Smaller institutions have also made their mark. Manonmaniam Sundaranar University in Tirunelveli has five scientists listed, while St. Xavier’s College, Palayamkottai, and VO Chidambaranar College in Thoothukudi contributed three and one scientist, respectively. These numbers, while modest compared to larger institutions, are noteworthy as they highlight the significant research being conducted in smaller universities and colleges across Tamil Nadu.
The Story of Scientists: Dr. S Selvam- A Rising Star in Research
One of the most remarkable stories from the Tamil Nadu contingent is that of Dr. S Selvam from VO Chidambaranar College in Thoothukudi. Dr. Selvam has made it to the world’s top 2% scientists list for the fourth consecutive year since 2021. His specialization in geology and environmental pollution, particularly concerning air and water sediments, has earned him 103 published research articles. In the 2024 rankings, Dr. Selvam improved his position significantly, climbing to 44,819 from 84,658 in the previous year. His work has garnered 633 citations and an h-index of 14, excluding self-citations, making him a highly respected figure in his field.
Dr. Selvam’s steady rise in the rankings is not only a personal achievement but also a reflection of the increasing recognition of environmental studies and geology in global research. His contributions underscore the importance of environmental sciences in tackling global challenges like climate change and pollution.
The success of Tamil Nadu’s researchers is no accident. Institutions across the state have been actively nurturing research programs through various forms of support from both the state and central governments. Manonmaniam Sundaranar University Vice Chancellor Chandrasekar emphasized this in an interview, noting the government’s role in providing assistance for research. “Professors have been encouraged to guide students and research scholars to develop novel ideas in their respective fields, as researchers need more citations to achieve higher ranks,” he said.
However, despite the growth in research output, several challenges remain. Educationalists and researchers point out that postgraduate students and scholars still require better guidance to fully capitalize on the available fellowships and grants. Although there has been a push from the state government to promote higher studies, research-oriented programs for scholars need to be strengthened further. Many researchers struggle to secure the necessary funding and fellowships, which are often essential for the continuation of their work.
One of the primary hurdles faced by researchers is the increasing competitiveness for fellowships and grants. Programs such as the Prime Minister’s Fellowship, Chief Minister’s Fellowship, Maulana Azad Fellowship for Other Backward Classes (OBC), Rajiv Gandhi Fellowship for SC/ST scholars, and various single-woman fellowships require candidates to clear competitive exams like the National Eligibility Test (NET) and the Graduate Aptitude Test in Engineering (GATE). While these fellowships provide much-needed financial support, the stringent requirements have made it more difficult for researchers to avail of these grants.
This competitive environment, while encouraging meritocracy, also adds pressure on students and young researchers who may struggle to balance research with the demands of preparing for these exams. Educationalists suggest that more research-oriented guidance programs should be curated to help scholars navigate these challenges and make the most of the available resources.
Tamil Nadu’s significant presence in Stanford University’s 2024 list of the world’s top 2% scientists is a proud moment for the state. The 537 scientists included in this prestigious ranking highlight the strength of the state’s educational and research institutions. From premier institutes like IIT-Madras and Vellore Institute of Technology to smaller colleges such as VO Chidambaranar College, the diversity of institutions represented underscores the breadth of research being conducted in the state.
However, while the inclusion of Tamil Nadu’s researchers in this global list is a cause for celebration, it also serves as a reminder of the need for continued support for research programs. Both state and central governments play a crucial role in fostering innovation, and efforts must be made to ensure that young researchers receive the guidance and resources they need to thrive.
As Tamil Nadu continues to climb the ranks of global scientific research, the focus must remain on nurturing the next generation of researchers, providing them with the tools and opportunities to contribute to the global scientific community. The future of science in Tamil Nadu looks bright, and with the right support, its researchers will continue to make significant strides in their respective fields.
