Research Experience

I worked as Visiting Assistant Professor at Stanford University, California, USA-94305 (October 2022 to April 2023).

I was involved in the work titled “Theoretical and Experimental Quantification of Error in Enzyme Kinetics Parameter of CRISPR-Cas12 and Cas13”. The objectives of the work are as follows: (1) To identify the sources of error in determination of Enzyme Kinetics Parameters (Kcat and KM) of the transcleaveage dynamics of CRISPR-Cas12 and Cas13. (2) To estimate the error theoretically in extracting the of Enzyme Kinetics parameter from response curve of cleaved reporter molecule by enzyme. (3) Experimental validation and comparison of the theoretically obtained results. Expected outcome of the proposal: We expect to identify and quantify the sources of error in the determination of Enzyme Kinetics Parameters (Kcat and KM) of CRISPR-Cas12 and Cas13. We also expect to estimate the sensitivity and uncertainty of these error sources. The current study is important to understand the transcleaveage dynamics of CRISPR-Cas12 and Cas13. It will lead the scientific community to a better clarity of Enzyme Kinetics Parameters of CRISPR. Furthermore, I worked on another project in parallel for desalination of water using novel microfluidic-based mixers in FCDI (Flow-electrode Capacitive Deionization). In this project, I am designing and analyzing various microfluidic mixers for better mixing and efficiency.

I worked as Post-Doctoral Fellow in the Department of Mechanical Engineering, Indian Institute of Technology Kanpur (IIT Kanpur) (Jan'19 to July’19).

I worked as Post-Doctoral Fellow with Prof. Anindya Chatterjee and Dr. Niraj Sinha in the Department of Mechanical Engineering, IIT Kanpur. My research problem was on the (a) Hysteresis modelling of bio-sensors and (b) Synthesis of nano-composites and its applications. I worked towards the identification and control of hysteresis with application to bio-sensors. Simultaneously I worked 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.

I worked as Early Post-Doctoral Fellow in the Department of Mechanical Engineering, Indian Institute of Technology Delhi (IIT Delhi) (July'18 to Sept’18).

I worked with Prof. Subhra Datta toward the extension of my PhD work as an Early Post-Doctoral Fellow. The title of the project was "patterned surfaces for drag reduction in micro-channels". I worked in the field of Micro-fluidics 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.

I worked as a project associate at Robert Bosch Centre for Cyber Physical System, Mechanical Engineering Department, Indian Institute of Science Bangalore (IISc Bangalore) (Nov'12 to Nov’13).

I worked under the guidance of Prof. Ashitava Ghoshal and Prof. G. K. Ananthsuresh as Research Associate in a project sponsored by Robert Bosch, at the M2D2 lab, Mechanical Engineering Department, IISc Bangalore. The project required real time cyber surgery and haptic visualization. I was doing the modeling and fabrication of an endoscopic simulator (with the Ph.D. student) using compliant mechanisms. The project involved using compliant mechanisms because of its 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 to the development of a haptic interface between the kit and operator. We also established the electronics and hardware for the device.

I worked as a research associate at Micro-fabrication Lab, Mechanical Engineering Department, Indian Institute of Technology Kanpur (IIT Kanpur) (Aug’12 to Nov'12)

I worked with Prof. Shantanu Bhattacharya 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.
