Dr. Gopi Nath Daptary

Biography

Dr. Gopi Nath Daptary is an Assistant Professor in the Department of Physical Sciences at the Indian Institute of Science Education and Research (IISER) Berhampur, where he joined in August 2026. He is currently establishing a Quantum Transport Laboratory at IISER Berhampur, focusing on experimental studies of quantum materials and low-dimensional systems.
Prior to joining IISER Berhampur, Dr. Daptary served as an Assistant Professor in the Department of Physics and Astronomy at the National Institute of Technology (NIT) Rourkela from 2023 to 2026. He received his M.S. and Ph.D. from the Indian Institute of Science (IISc), Bengaluru, in 2018. His doctoral research focused on Electronic Transport in Low-Dimensional LaAlO₃/SrTiO₃ Heterointerfaces, where he investigated electronic transport phenomena in oxide heterostructures. Following his Ph.D., Dr. Daptary worked as a Postdoctoral Researcher at Bar-Ilan University, Israel, from 2018 to 2021, where he studied quantum materials and interfaces involving disordered superconductors. He subsequently joined the Tata Institute of Fundamental Research (TIFR), Mumbai, as a Visiting Fellow from 2021 to 2022, where he worked on the electronic properties of Kagome metals. Before joining NIT Rourkela, he was a Postdoctoral Researcher at the Okinawa Institute of Science and Technology (OIST), Japan.
His research interests broadly encompass experimental quantum transport in quantum materials, oxide thin films and heterostructures, disordered superconductors, low-temperature physics, and conductance fluctuations (noise). His research combines low-temperature transport measurements with nanofabrication and noise spectroscopy to investigate novel electronic phenomena in quantum and disordered materials.
At IISER Berhampur, his research group will focus on developing advanced experimental capabilities for quantum transport and low-temperature measurements and investigating emergent electronic phenomena in quantum materials, superconducting systems, and nanoscale heterostructures.
