Brief Bio:
Dr. Subhamita Sengupta is a postdoctoral fellow in the Department of Condensed Matter Physics and Material Sciences at the Tata Institute of Fundamental Research (TIFR), Mumbai. She completed her BSc in 2013 from Asutosh College, Kolkata affiliated with the University of Calcutta) and earned her MSc in 2016 from Jadavpur University. She was awarded her PhD in June 2022 from the S. N. Bose National Centre for Basic Sciences, Kolkata. Additionally, she served as a visiting fellow at the same institution from August 2021 to July 2022.
Dr. Sengupta’s research focuses on low-temperature electrical and magnetotransport, vortex dynamics in superconductors, and interface phenomena in complex oxides. She has published in reputed international journalsand received the INSPIRE scholarship during her undergraduate studies.
As a Fulbright-Nehru Postdoctoral Research Fellow at Harvard University, Dr. Sengupta is leveraging advanced techniques developed by Prof. Jennifer Hoffman’s team, combining scanning tunneling microscopy (STM) and magnetic force microscopy (MFM), to study superconducting vortices hosting Majorana zero modes — a cornerstone of topological quantum computing. Her research focuses on detecting magnetic field gradients between proximate vortex cores using MFM to determine the parity states of overlapping Majoranas, a critical step toward achieving stable qubit operations and topologically protected quantum logic.
