I am a Ph.D. student at the Indian Institute of Science, Bangalore. I have been working on nonlinear dynamics of Nano Electromechanical Systems (NEMS) for the last six years. During this period have designed and implemented various experiments on NEMS

My research work has mainly focused on developing nanoelectromechanical sensors with strain tunability, where I have studied the effect of strain on linear and nonlinear dynamics, mode coupling, dynamic range, limit of detection, and quality factor of resonant sensors. With the devices fabricated during this work, I have demonstrated the most responsive pressure sensing using a resonant sensor, the use of resonant sensors as bifurcation amplifiers and as logic gates and the characterization of dynamic strain change of the substrate. I have built a strong background in device design, nanofabrication, ultrasensitive measurement, design of experiments, and scientific data analysis.

I have extensive experience in fabricating 2D material-based devices in a class 100 cleanroom, using various tools such as e-beam, photolithography, and wet/dry etching techniques to pattern sub-micrometer or few micrometers-wide features on a silicon wafer. I have also developed fabrication process flows and optimized recipes for optimum yield. In addition, I have expertise in characterizing fabricated devices using SEM, AFM, and RF electrical characterization techniques.

I have hands-on experience in detecting resonance in nanomechanical systems, using signal generators, LIA, and passive components such as RF mixers, splitters, and bias tees. I am also experienced in studying mode shapes of silicon diaphragms, using laser Doppler vibrometry. I can set up scientific instrumentation for experiments, automate experiments using Python/Matlab scripting, efficiently manage experimental data, process and visualize experimental data, and produce reports to describe the findings from the data. Furthermore, I have hands-on experience in building vacuum systems, and designing and building custom vacuum chambers that fit on a PCB and have an optical window. I have designed PCBs for various requirements during my research work and have built specialpurpose attachments, jigs, and mechanisms to suit the requirements of the experiments. I have also solved many problems involving nanofabrication, process flow development, and optimization, and have built many experimental setups for ultrasensitive detection of vibrations.

I have also developed a keen interest in computer science during my spare time. I am a self-taught programmer in Python, JavaScript, and C++. I have used these programming skills primarily in instrument control and data analysis of my experiments on NEMS.
