Nilgiris-based environmental researcher Dr. Ashokkumar Veeramuthu has once again secured a spot among the World’s Top Scientists, a global ranking jointly compiled by Stanford University and Elsevier Publishers. This marks his third consecutive recognition — in 2023, 2024, and 2025 — a distinction few Indian scientists have achieved.

The honour celebrates his sustained contributions to research that bridges science and society — tackling pressing global challenges such as waste management, pollution reduction, and sustainable energy.

Science for society

Driven by the belief that science should serve people, Dr. Ashokkumar’s work focuses on developing microalgae-based clean fuels, innovative plastic recycling technologies, and efficient waste management systems adaptable across economies. His solutions blend academic rigour with practical application, aiming to make sustainability both achievable and scalable.

His global contributions have also earned him the ‘Brain Pool: Visiting Global Scientist Award’ from the National Research Foundation of Korea, recognising scientists who advance sustainable, applied research worldwide.

From the Nilgiris to global acclaim

A product of Government schools in Tamil Nadu’s Nilgiris district, Dr. Ashokkumar’s rise to international recognition underscores the transformative power of persistence and purpose-driven research. He has authored over 130 research papers in leading international journals and collaborates with 18 universities worldwide, advancing research that unites innovation and impact.

Currently, he serves as Professor and Head of the Centre for Waste Management and Renewable Energy at Saveetha University (SIMATS), Chennai, and holds visiting professorships at Chulalongkorn University (Thailand), University Technology Malaysia, and several top Korean universities.

A reflection of Indian science’s growing reach

Dr. Ashokkumar’s consistent inclusion in Stanford’s global list not only highlights his individual excellence but also reflects the rising influence of Indian research on the world stage. His journey — from a small town in the Nilgiris to global recognition — stands as a testament to how homegrown innovation and dedication can shape the world’s sustainability agenda.
