Current Research Interests

My research interest is in the field of plasma diagnostics especially fusion spectroscopy. My present research interest is in the design and development of a Near-Infrared Spectroscopy diagnostics system for edge and divertor plasma spectroscopy of Aditya-U tokamak for plasma parameters and influx measurement. I am also interested in the development of a novel system for direct measurement of plasma potential and its fluctuations in the edge region of fusion machines using laser heated emissive probes. .
