Dr. Bhaskar Singh is working as Associate Professor in the Department of Environmental Sciences. Dr. Sachin Kumar is working as Assistant Professor in the Department of Energy Engineering and Dr. Arnab Sankar Bhattacharyya is also working as Assistant Professor in the Department of Metallurgical and Materials Engineering, Central University of Jharkhand, Ranchi.

Name of all three researchers has been recently featured in the Stanford University’s list of “World’s Top 2% Scientists” published by Elsevier on 19^th September 2025 (doi: 10.17632/btchxktzyw.8).

According to the Stanford – Elsevier report, a publicly available database of over 100,000 top-scientists has been created that provides standardized information on citations, h-index, co-authorship adjusted hm-index, citations to papers in different authorship positions and a composite indicator. The selection is based on the top 100,000 by C-scores (number of citations, excluding self-citations) or a percentile rank of 2% or above. Separate data are shown for career-long and, separately, for single recent year impact. Scientists are classified into 22 scientific fields and 174 sub-fields according to the standard Science-Metrix classification. Dr. Bhaskar Singh’s name is in the second list for the fifth consecutive year in the discipline ‘Energy (sub-field-1)’ and ‘Biotechnology (sub-field-2)’. Dr. Sachin Kumar appeared for the third time on single year impact list in the discipline ‘Energy (sub-field-1)’ and ‘Environment (sub-field-2)’. Dr. Bhattacharyya’s name appears in the discipline ‘Applied Physics (sub-field-1)’ and ‘Materials (sub-field-2)’for the first time on single year impact list.
