"We work with smallest & finest materials to capture the fastest dynamics".


The objective of the research in our group is exploring novel physics in quantum and 2D materials, which also lead to future nano-electronics and photonic applications. Particularly, our group focuses on 2D van der Waals materials, intense luminescence materials, and materials for THz applications. Our strength is studying the fast dynamics using high intense and ultrafast lasers with broad spectral range, including UV-VIS, IR and THz. Nonlinear optical effects in the materials due to high-intensity laser pulses drive the research towards a deep understanding of light-matter interactions.

I hailed from Haryana and completed Bachelor’s with Physics, Chemistry, and Maths at C. M. K. College, Sirsa, Haryana. I have completed M. Sc. Physics from Ch. Devi Lal University, Sirsa, Haryana.

My interest in the research drove me to join as a Ph. D student at UPG(Ultrafast Physics Group), IITJ, in Dec 2019 with UGC-JRF. I would like to pursue my research in the dreamland of 2D materials for photonic applications. Also, my interests extend to the fields of Nonlinear Optics, Ultrafast Spectroscopy, and Light-Matter Interactions at Nanoscale.




I have done my Bachelors from Odisha and subsequently completed my masters in Physics at Berhampur University.

The fascinating field of Optics gave me an excellent opportunity to join the Ultrafast Physics Group (UPG) at the Department of Physics, IIT Jodhpur, in August 2020 as a Ph.D. student. I would like to explore the emerging research directions in ultrafast lasers, Nonlinear Optics, and 2D materials for their optical and optoelectronic applications, both in experimental and theoretical aspects.
