Bangalore: If you take the output of research articles India is ranked among top 10 in the world. Whereas when it comes to the quality of the research articles it is marked among the top 20 list. It, however, lagged behind China and Brazil. Michiel Kolman, senior vice-president, Global Academic Relations at Elsevier said that India was strong, based on leadership articles, in chemistry (35 percent), engineering (18 percent), mathematics and physics (11 percent) and biology (10 percent). The most productive institutions in the country were the IITs, the IISc, and the CSIR institutions. The only university among the top 10 was the University of Delhi. Research was very strong in physics, chemistry, engineering, earth science, biology, biotechnology and infectious diseases in India. The areas in which the nation needs to improve are computer science, social science, health sciences, medicine, and brain research. Almost all institutes had shown a steady growth in publication of research articles, but there was some catching up to do with the best in the world in terms of quality. The country has to focus more on bringing out articles that are really quality oriented and the Top scientists in every discipline (based on quality articles) could be identified using the zoom in tool and narrowing subject-wise specialists. It would also help in identifying the strong areas of each university and explore the scope for collaboration between institutes.
