Research area: Topological phases in van der Waals and 2D materials like 1T-TiSeâ‚‚, 1T-TaSâ‚‚ and few layer CrS2 devices.

My work focuses on investigating charge density waves (CDW), topological Hall effects, and nonlinear Hall effects using an advanced low-temperature (cryogenic) electronic transport setup. I possess extensive expertise in measurements and technical troubleshooting skills in operating a cryofree 300 mK (He3)/1.6 K cryostat (Teslatron). I have also developed LabVIEW-based programming for deep-level transient spectroscopy (DLTS) technique to study defect levels in quantum materials and dielectric constant (Cp-tan delta) measurements in cryogenic environments. Additionally, I collaborate on developing CPW-based resonator circuits to qubits for quantum computation using laser based optical lithography and chemical etching. With another group, I have successfully investigated Shubnikov-de Haas oscillations in thin films by low-temperature electrical transport.

Research area: Transport phenomena in topological materials
I am a Senior Research Fellow under the DST Nano-Mission and hold a postgraduate degree in Physics from IIT Guwahati. My research focuses on quantum materials, particularly topological systems, and charge density wave phenomena. I have extensive expertise in cryogenic systems, nanofabrication and advanced measurement techniques, including the nonlinear Hall effect, Seebeck measurements and noise spectroscopy. As a recipient of the INSPIRE Fellowship and multiple research awards in international conferences, I am dedicated to advancing the understanding of the interplay between topology, magnetism, and correlated phenomena.

​
​I completed my B. Sc. (Honours) in Physics from the University of Burdwan. I qualified JEST 2017 in Physics and joined the Integrated Ph.D. Programme in Physics at S.N.B.N.C.S. I obtained M. Sc. in Physics in 2019 and joined as a Ph. D. Research Fellow. I also qualified JAM 2017, GATE 2020, and GATE 2021. My research interests are centered on the low-temperature electro-transport and magneto-transport study of van der Waals layered magnetic materials and their heterostructures. I investigate the transport properties of emerging low-dimensional superconducting materials. I have expertise in handling cryogenic millikelvin systems, device fabrication, dry-transfer of 2D flakes, assembling heterostructures, and performing various measurement techniques, including anomalous Hall effect, magnetoresistance, micro-Raman spectroscopy, and electron spin resonance spectroscopy.
