Work Experience


  1. Working as Assistant Professor in the Department of Mechanical Engineering at IIITDM Kancheepuram, Chennai from 2019 to present.

  2. Worked as Assistant Professor (TEQIP Faculty, Sponsored by MHRD and World Bank) in the Department of Mechanical Engineering, THDC-Institute of Hydropower Engineering and Technology, New Tehri, Uttarakhand (2018) for a semester.


  1. Worked as Post-Doctoral Fellow in the Department of Mechanical Engineering, IIT Kanpur (2018 to 2019): I worked as Post-Doctoral Fellow with Prof. Anindya Chatterjee and Dr. Niraj Sinha in the Department of Mechanical Engineering, IIT Kanpur. I am working on the (a) Hysteresis modelling of bio-sensors and (b) Synthesis of nano-composites and its applications. I wish to develop a research activity in the not yet mature field of identification and control of hysteresis with application to biosensors. Simultaneously I am working on the synthesis of BN and BCN nano-particles/sheets. These particles have applications as nano-composites and micro-systems for energy and packaging industries.

  2. Worked as Early Post-Doctoral Fellow in the Department of Mechanical Engineering, IIT Delhi (2018): I worked toward extension of my PhD work as Early PDF. I worked in the field of Microfluidics and Laser texturing. I analyzed the effect of texturing on the fluid flow behavior of fluids in the textured micro-channels. I also studied the flow anisotropy in the micro-channels due to textured surfaces.

  3. Worked as a project associate at Robert Bosch Centre for Cyber Physical System, Mechanical Engineering Department, Indian Institute of Science Bangalore (IISc, Bangalore) (2012-2013): I was involved in a project sponsored by Robert Bosch, at the M2D2 lab, Mechanical Engineering Department, IISc Bangalore. The project required a real time cyber surgery and haptic visualization. I was doing the modeling and fabrication of endoscopic simulator (with the Ph.D. student) using compliant mechanisms. The project involved using compliant mechanisms because of suitability in small size with easy fabrication and no parts to assemble. I was doing the design, simulation, fabrication, and testing of the compliant mechanism. A prototype was fabricated using sensors, manipulators, and compliant mechanisms. Significant teamwork was required to visualize and model the body parts. I also contributed toward the development of a haptic interface between the kit and operator. The Ph.D. students helped me in establishing the electronic and hardware for the device.

  4. Worked as a research associate at Micro-fabrication Lab, Mechanical Engineering Department, Indian Institute of Technology Kanpur (IIT Kanpur) (2012): I worked in the field of MEMS and Microfluidics at IIT Kanpur. We fabricated and integrated various micro devices. We have made a peristaltic pump operated by the micro valves. A solenoid valve in PDMS for micro fluid control was fabricated in-house. My contribution to this project was to analyze and fabricate the assembly. I wrote a program in MATLAB for automated image analysis of solenoid valve. The capability of code is in finding the eccentricity of the valve from the central axis. The program takes a picture of the valve from the web cam and estimates the defects, eccentricity, and deflection in the micro valve. We characterized various solenoid valve with the MATLAB code to get an optimized and error free solenoid valve.
