Prof. Meththika, Prof. Neelika and Dr. Anushka ranked among the top 2% of Scientists in the world by Elsevier BV and Stanford University

Three researchers from the University of Sri Jayewardenepura, Prof. Meththika Vithanage, Dr. Anushka U, Rajapaksha and Prof. Neelika Malavige are ranked among World’s Top 2% Scientists in the 2020 List of outstanding researchers prepared by Elsevier BV, Stanford University, USA. This is the newest data-update for “Updated science-wide author databases of standardized citation indicators”. This ranking has been standardized using information from citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator.

There are 24 scientists ranked in this World’s Top 2% Scientists list from various institutes: University of Sri Jayewardenepura, International Water Management Institute, University of Peradeniya, Wayamba University of Sri Lanka, University of Colombo, University of Kelaniya and the University of Jaffna.  Out of 24 Sri Lankan scientists, 3 of them are from the USJ, Prof. Meththika Vithanage, Dr. Anushka U, Rajapaksha and Prof. Neelika Malavige.

The use of citation metrics has become widespread but challenges relate to what citations and related metrics fundamentally mean and how they can be interpreted or misinterpreted as a measure of impact or excellence. Many other problems are of a technical nature and reflect a lack of standardization and accuracy on various fronts. Since there is no large-scale database that systematically ranks all the most-cited scientists in each and every scientific field to a sufficient ranking depth. Moreover, self-citations are not excluded from the existing rankings. However, as with all other ranking systems, there can be negatives in this particular ranking system, though it has been recognized throughout the world.
