At Bhabha Atomic Research Centre (BARC), I develop optical and laser-based gas-sensing systems using QEPAS, 2f-WMS and QCL technologies. My work includes an SF₆ detector with ~80 ppb detection, with technology-transfer documentation underway.

I also developed an NH₃ 2f-WMS detector with <100 ppb detection capability (3σ) for breath-analysis research and potential ammonia-sensing applications. I contributed to field validation of an amplitude-modulated SF₆ detector for industrial leak detection.

I supported development and technology transfer of a D/H isotope-ratio mass spectrometry system using Chromium Reduction-based sample preparation. I also supported modifications, deployment and lifecycle maintenance of approximately 14 systems across Heavy Water Plants.

My work includes designing a Miniature Vacuum Controller and developing optical systems such as a CEAS-based water-isotope analyser. I’ve also helped establish Class 100 cleanroom and laboratory infrastructure, and coordinate technical requirements, procurement, fabrication, testing and deployment with scientific teams, vendors and end users.
