Biosketch

Dr. Rahul Kumar is currently working at IIT Bhubaneswar as Assistant Professor in the School of Mechanical Sciences.
 
Hailing from Nalanda district and raised in Patna, Bihar, Dr. Kumar completed his early education in Patna before pursuing his B.Tech. in Mechanical Engineering (2015) at Cochin University of Science and Technology, Kochi. He further advanced his studies at IIT Madras, where he earned an MSc (Engg.) and a PhD (2022) with a dissertation on the “Analysis of bladed discs with spatial random inhomogeneities.” 
 
His research interests span Mechanical Vibration, Nonlinear & Non-Smooth Dynamics, Uncertainty Quantification, Energy Harvesting, and Reduced Order Modelling. Dr. Kumar has also served as a Visiting Assistant Professor at Georgia Tech, where he worked closely with Prof Rachel Kuske on targeted energy transfer using vibro-impact systems. During his stay at Georgia Tech, he also collaborated with Prof. Daniil Yurchenko at University of Southampton, UK and carried out experimental studies on TET through vibro-impact systems.
 
At IIT Bhubaneswar, Dr. Kumar is eager to pursue interdisciplinary research aimed at delivering cutting-edge solutions for the defense, automobiles and aerospace related sectors.
 
Beyond academics, Dr. Kumar has a passion for Hindi literature and enjoys exploring new places around the world.
