About

I am currently a Postdoctoral Fellow at the Technion – Israel Institute of Technology, Haifa, where I work on YBCO nanowire-based photodetectors. I completed my PhD in Physics from the Indian Institute of Technology (IIT) Delhi, where my research focused on high-temperature superconductor-based step-edge Josephson junctions and superconducting quantum interference devices (SQUIDs) for geophysical applications.
My research expertise includes thin-film deposition using pulsed laser deposition (PLD), sputtering, and e-beam deposition, as well as device fabrication techniques such as ion beam milling, reactive ion etching (RIE), electron beam lithography, and photolithography. I also have extensive experience in electrical, magnetic, and optical characterization at cryogenic temperatures.
