I am a Postdoctoral Fellow working in quantum nonlinear optics, currently conducting research at the Weizmann Institute of Science. My primary research focus is on engineering atomic states through pump-probe spectroscopy techniques. In particular, I investigate the van der Waals interactions between Rydberg polaritons to study photon-photon interactions, which do not typically occur in free space. These interactions can manifest as attractive, repulsive, or scattering phenomena.

At the Weizmann Institute of Science, I have successfully demonstrated the implementation of strong photon-photon interactions, leading to the observation of nontrivial physical phenomena such as quantum vortices, vortex lines, vortex rings, and higher-order bound states of photons.

During my doctoral studies, I concentrated on the coherent properties of atomic media, including electromagnetically induced transparency (EIT), electromagnetically induced absorption (EIA), Autler-Townes (AT) splitting, optical rotation, subluminal light propagation, precision spectroscopy, and magnetometry. I conducted both experimental and theoretical investigations in this area.

As the first doctoral student of the "Laser Spectroscopy Laboratory" at the Saha Institute of Nuclear Physics, I successfully established experimental setups to study coherent interactions within atomic media using laser fields.

Prior to my doctoral work, I completed my master's degree at the Indian Institute of Technology Madras and obtained my undergraduate degree from Presidency College, Kolkata, under the University of Calcutta.
