S  Majumder joined IIT Kharagpur in 2007 and developed an Atomic, Molecular and Ultracold Atomic Gas research group at IIT-Kharagpur with funding from national and international agencies. His major contributions are the first principle understanding of orbital angular momentum transfer from light to quantum matter, understanding of crystalline phase in a superfluid, like Bose-Einstein condensate, and exploring optimization of variational quantum algorithms. Currently, he is working on different topological phases of dipolar and spinor ultra-cold atomic gasses along with quantum scrambling. 11 of his PhD students have received doctoral degrees and the remaining 13 research scholars are pursuing their doctoral research under his guidance. He has published 75 papers in internationally refereed journals.

Basudev Lahiri is an Assistant Professor at the Electronics Engineering Department of IIT Kharagpur. Prior to this, he was a Lord Kelvin Adam Smith Fellow at the University of Glasgow, United Kingdom and a Researcher Associate at the National Institute of Standards & Technology (NIST), Gaithersburg, United States. Dr Lahiri’s speciality lies in Nanofabrication and Optical characterization of various nano-bio materials. He has over fifteen years of experience in various nanofabrication techniques as applied to Nano Bio Photonics. He combines his expertise both as a designer of nanophotonics devices and as a developer of new optical characterization techniques to produce novel sensor technologies for the early detection of diseases. Presently, he leads the NanoBioPhotonics research group at IIT Kharagpur.
