Arockia Sherlin J. is a Ph.D. Research Scholar at the Nanotechnology Research Centre (NRC), SRM Institute of Science and Technology, Kattankulathur, Chennai. She completed her B.Sc. in Physics from Holy Cross College (Autonomous), Tiruchirappalli, and her M.Sc. in Physics from St. Joseph's College (Autonomous), Tiruchirappalli. Her master's research focused on the synthesis and characterization of Carbon Quantum Dot/Graphitic Carbon Nitride (CQD/g-C₃N₄) nanocomposites for photocatalytic applications. Her current Ph.D. research focuses on the fabrication of a highly sensitive and reliable H₂O₂ sensor by integrating chemiresistive and thermoelectric sensing technologies for real-time applications. Her research interests include gas sensors, chemi resistive sensors, thermoelectric sensors, nanomaterials, functional materials, and environmental monitoring.
