Dr. Rajiv Tiwari is currently Professor in the Department of Mechanical Engineering, Indian Institute of Technology Guwahati, where he has been working since 1997. He completed his PhD from IIT Kanpur in the area of Rotor Dynamics in 1997. Just after PhD, he worked in Regional Engineering College, Hamirpur (Himachal Pradesh), India for a year during 1996- 1997. He worked as Research Officer for one year in 2001 in University of Wales, Swansea, UK and as DAAD Fellow in Technical University of Darmstadt Germany in 2011 for two months. Dr Rajiv Tiwari works in the area of Rotordynamics and Design of Rolling Bearings. He has more than 250 papers in international and national journals and conferences. He has successfully organised number of national and international conferences and short terms courses in the area of vibrations and rotordynamics. He has authored two book (i) Rotor Systems from CRC Press, USA in 2017 and Simple Rotor Analysis through Tutorial Problems from CRC Press, USA in 2023. He has developed web and video-based courses under NPTEL on Mechanical Vibration and Rotor Dynamics. He has been offering consultancy for last several years to Indian industries, like Indian Space Research Organization (ISRO), Trivandrum; Combat Vehicle R&D Establishment (CVRDE) Chennai; Tata Bearings, Kharagpur; Gas Turbine Research Establishment (GTRE), Bangalore, NBC Bearings; apart from other local industries in the northeast of India. Prof. Tiwari has been featured consecutively for last five years among World’s Top 2% Influential Scientists List created by Stanford University. He is Associate Editor to the Journal of Vibration and Control (JVC), Sage Publications, and Journal of Vibration Engineering and Technology (JVET), Springer Nature Publications. Also, he is in Worldwide Technical Committee on Rotor Dynamics of International Federation of Machines and Mechanisms (IFToMM). In 2022, he has been interviewed by magazine Tribology & Lubrication Technology, USA for its cover story on Artificial Intelligence for Real-World Mechanical Systems. Recently, he has been included in The Bearings Sectional Committee, PGD 13, of Bureau of Indian Standards (BIS), which is responsible for the development of the national and international standards on the ‘Magnetic Bearings’, 'Aerospace Bearings' and 'Railway Bearings’.
