Investigated the effectiveness of utilizing 1D nanofiber morphology to develop chemiresistive gas sensors for detecting hazardous and toxic gases.
Improved the sensor's performance characteristics, including sensitivity, selectivity, and response time, through the use of 1D nanofibers as the sensing material.
Contributed to the development of more advanced and effective gas sensors that can improve workplace and environmental safety.
Conducted research aimed at enhancing gas detection and monitoring for increased safety in hazardous environments.
Demonstrated knowledge and skills in materials science and chemical sensing, as well as research methodology and data analysis.

University of Petroleum and Energy Studies

Dehradun 2018 to 2020 Dissertation,

Advisor: Dr. Vijaya Parthasarathy

Developed a 17-lump kinetic model using MATLAB for an Industrial Fluid Catalytic Cracking Unit (FCCU) that accounted for catalyst deactivation due to coke deposition and included 199 kinetic parameters.
Used simulation-based optimization to identify optimal operating conditions and catalyst design, improving the efficiency and profitability of the FCC process. • The kinetic model can predict FCCU performance under different operating conditions and optimize the process, making simulation a powerful tool for developing, optimizing, and designing FCCU systems.
Simulation is critical in developing and optimizing FCCU systems, and software such as MATLAB is used for optimizing the FCCU.
Simulation is a powerful tool for designing new FCCU systems, as it allows for the prediction of FCCU performance under different operating conditions and the optimization of the process.
