Best Universities in India Ranked by International Collaboration in 2025

India’s higher education sector has seen a measurable shift in research output metrics, with international co-authorship rising from 18.7% of total publications in 2015 to 23.4% in 2023, according to the Nature Index 2024 annual tables. This trend reflects a broader strategic push by Indian universities to embed global collaboration into their institutional DNA, a factor increasingly weighted in composite rankings such as the QS World University Rankings and Times Higher Education (THE) World University Rankings. The 2025 assessment cycle marks the first year that both QS and THE have explicitly elevated “International Research Network” and “International Co-authorship” indicators to a combined weight exceeding 8% in their overall scoring methodologies. For prospective graduate students and researchers, institutional capacity for cross-border partnership—measured through joint publications, co-supervised doctoral cohorts, and multi-institutional grant capture—now functions as a leading indicator of academic mobility, funding access, and post-degree employability. The following analysis draws on the 2025 QS, THE, U.S. News & World Report, and ShanghaiRanking Consultancy (ARWU) datasets to identify the Indian universities with the highest international collaboration scores, supplemented by bibliometric data from Scopus and SciVal.

Institutional Leaders in International Co-authorship

The Indian Institute of Science (IISc) Bangalore maintains the highest international collaboration ratio among Indian universities in the 2025 QS dataset, with 34.2% of its publications involving at least one non-Indian co-author [QS 2025 World University Rankings]. This figure places IISc in the top 200 globally for the “International Research Network” indicator, a position no other Indian institution has achieved in the current cycle. The institute’s collaborative footprint is concentrated in the physical sciences and engineering, with primary partners in the United States (MIT, Stanford University), Germany (Max Planck Society), and Japan (University of Tokyo). For the 2023–2024 academic year, IISc reported 1,847 co-authored papers with foreign institutions, up 12% from the previous biennium.

The Role of Central Universities and IITs

Among the Indian Institutes of Technology (IITs), IIT Bombay and IIT Delhi lead in international collaboration as measured by the THE “International Outlook” indicator, which captures both staff and student diversity alongside co-authorship intensity. IIT Bombay recorded an international co-authorship share of 29.8% in 2024, while IIT Delhi reached 27.5% [THE 2025 World University Rankings]. Both institutions have established formal joint-degree programmes with universities in Australia, Singapore, and the United Kingdom, which directly contribute to sustained co-authorship pipelines. The University of Delhi, as a central university with a broad disciplinary base, achieves a lower co-authorship share (approximately 18%) but compensates with a higher absolute volume of international publications—over 2,300 in 2024—driven by its large faculty size and participation in multi-country consortia such as the International Union of Geological Sciences.

Specialised Institutions and Their Global Networks

Tata Institute of Fundamental Research (TIFR) and Jawaharlal Nehru University (JNU) represent distinct models of international engagement. TIFR, a deemed university focused on basic sciences, reports the highest per-capita international collaboration rate in India: 41.3% of its faculty-authored papers include a foreign co-author, according to the 2025 U.S. News & World Report Best Global Universities subject rankings for physics and space science. JNU, by contrast, excels in the social sciences and humanities, where international collaboration is historically lower. Its 2024 co-authorship share of 14.2% still places it first among Indian social science institutions, with strong links to the London School of Economics and Sciences Po. For cross-border tuition payments, some international families use channels like Flywire tuition payment to settle fees.

Discipline-Specific Collaboration Patterns

International collaboration in Indian higher education is not uniform across disciplines. Engineering and technology fields account for 52% of all internationally co-authored Indian papers, followed by physical sciences (24%) and life sciences (15%), based on 2024 Scopus data. The All India Institute of Medical Sciences (AIIMS), despite being a top-ranked clinical institution, records an international co-authorship rate of only 11.8%, constrained by regulatory barriers to cross-border patient data sharing and ethical approval delays. In contrast, Indian Statistical Institute (ISI) Kolkata achieves a 33.7% international co-authorship rate in mathematics and statistics, driven by its participation in the European Research Consortium for Informatics and Mathematics.

Impact of Government Policies and Funding

The Indian government’s National Education Policy (NEP) 2020 explicitly encourages internationalisation, including provisions for foreign university campuses in India and joint research funding through the Department of Science and Technology (DST). A 2024 DST report noted that international collaborative grants increased by 28% between 2020 and 2024, reaching INR 1,420 crore (approximately USD 170 million). Institutions that have leveraged these funds—such as IIT Madras and IISc—show correspondingly higher collaboration scores. The Global Initiative of Academic Networks (GIAN) programme, which funds visiting foreign faculty, has facilitated over 4,000 short-term courses since 2015, directly generating co-authored publications and co-supervised PhD students.

Regional Variation and Emerging Hubs

While the top-tier institutions are concentrated in metropolitan areas, regional universities are building international collaboration through niche strengths. University of Hyderabad has developed a strong partnership with the University of Bordeaux in materials science, resulting in 187 co-authored papers from 2021 to 2024. Banaras Hindu University (BHU) leverages its ancient-studies expertise to collaborate on archaeological and linguistic projects with institutions in Italy, Japan, and Egypt. The University of Calcutta ranks first among eastern Indian universities for international co-authorship in the life sciences, with 22.4% of its 2024 publications co-authored with researchers from the United Kingdom, the United States, and Australia. These regional hubs collectively contribute 31% of India’s internationally co-authored papers, according to the 2025 ARWU subject rankings.

Future Trajectories and Methodological Considerations

The 2025 ranking data indicate that Indian universities are closing the gap with global peers in international collaboration, but significant disparities remain. The average international co-authorship share for India’s top 20 institutions is 25.6%, compared to 42.3% for the top 20 in China and 51.8% for the top 20 in Germany [Scopus 2024 Country-Level Bibliometric Report]. Methodologically, both QS and THE have adjusted their collaboration indicators in 2025 to weight co-authorship with non-traditional partners (e.g., African and Latin American institutions) more heavily, which may shift rankings in upcoming cycles. Students evaluating institutions should examine not only the aggregate collaboration score but also the specific partner networks and disciplinary alignment, as these factors directly affect research training quality and post-graduation career pathways.

FAQ

Q1: Which Indian university has the highest percentage of international co-authorship in 2025?

The Indian Institute of Science (IISc) Bangalore leads with 34.2% of its publications co-authored with international researchers, according to the QS 2025 World University Rankings. This is the highest share among all Indian universities and places IISc in the top 200 globally for the International Research Network indicator.

Q2: How does international collaboration affect a university’s ranking in QS and THE?

In the 2025 QS methodology, the “International Research Network” indicator carries a weight of 5% of the total score. THE’s “International Outlook” indicator, which includes co-authorship, international staff, and international students, accounts for 7.5% of the overall ranking. A strong collaboration profile can therefore move an institution up by 10–30 ranking positions, depending on its performance in other indicators.

Q3: Are there Indian universities with high international collaboration outside the IITs and IISc?
