Kalpajit Roy

Kalpajit Roy is a PhD researcher at Institut Néel (CNRS/UGA, Grenoble), supervised by Benjamin Sacépé and Hervé Courtois. He completed the Erasmus Mundus Joint Master’s in Nanoscience and Nanotechnology (EMMNANO, 2025) at KU Leuven and Université Grenoble Alpes, and holds a B.Sc. (Honours) in Physics from the University of Delhi. His current research develops gate-tunable graphene quantum Hall Josephson junctions and targets control of chiral Andreev edge states in the ν = 2 regime, aiming to probe topologically protected states in graphene–superconductor hybrids.
