Dr. Rajendra Kumar is an Assistant Professor in the Mechanical Engineering Department at Thapar Institute of Engineering & Technology, India. He is associated with the Machine Design group of the Department. Rajendra completed his post-graduation from IIT Delhi and Ph.D. from IIT Roorkee. His Ph.D. work has been focused on the enhancement of the dynamic performance of electrostatic MEMS through controlling the residual oscillations and contact bounces in the pre-pull-in and post-pull-in regions, respectively, using a feed-forward control technique. He extensively worked in the field of mechanics of MEMS and structural optimization. During the course of his Ph.D. work, he becomes very interested in dynamic system modeling and optimization of the microstructure. He has been especially intrigued by the study of the design of vibration control techniques to control robotic systems.  His research interest is a broad area of applied mechanics, nonlinear vibration, and control. In particular, my interest is in dynamical system modeling, simulation, control, and optimization of engineering structures.

He is active in supervising Masters and Ph.D. students for their dissertation/thesis. The proposed component of the research is expected to serve as vital inputs to the researchers and practitioners working in the domain of dynamics and control of MEMS actuators.  Therefore, in the coming future, he wants to accomplish these proposed components of research with the involvement of students. The results of the investigations will be disseminated in the form of scientific publications.

His research work is published in various peer-reviewed journals of international repute such as the Journal of Micromechanics and Microengineering, Microsystems Technologies, Micro and Nanosystems, Composite structures, and Journal of Vibrations and Controls. There are 13 research articles and 04-conference publications relevant to the dynamics of microstructures and fracture mechanics.
