Ranjan Jha

About

Hi, my name is Ranjan Jha and I specialize in Robotics. Now I work as a scientist at CSIR- Central Scientific Instruments Organisation in the BioMedical Instrumentation division. I love working with passionate people and sharing what I've learned with them.

I was a postdoctoral fellow at Polytechnique Montreal, Canada in the Department of Mechanical engineering. I received my Ph.D. in robotics (as Erasmus Mundus fellow) at IRCCyN, Ecole Centrale de Nantes, France. My thesis focuses on the different aspects which are associated with the planning of a task for the parallel manipulators. Presently I am working to develop the different indigenous medical devices. My research involves Biomedical Instrumentation, Gröbner based computations and Cylindrical Algebraic Decomposition algorithm to compute and study the workspace, singularities, and joint space of the parallel robots, which further extended to check the feasibility of any given trajectories in the workspace.

In the past, I worked as Research Scholar at Institut de Recherche en Communications et Cybernétique de Nantes (IRCCyN), UMR CNRS 6597, France. Also, I worked as a quick hire scientist with CSIR – Central Scientific Instruments Organisation. There I was working on the implementation of motion transfer and haptics for the surgical robots. I received my master’s degree in Advanced instrumentation Engineering from the Academy of Scientific and Innovative Research.
