Vijay Singh

Research Fellow

Dr Vijay Singh is an experimental physicist. He joined the ultracold strontium group in January 2021. He conducts research in several different areas such as the measurements of inelastic and reactive collisions of cold atoms and molecules, cryogenic molecular beam techniques, moving trap Zeeman deceleration of cold atomic and molecular beams, precision spectroscopy of cold atoms and molecules, and strontium optical lattice clocks. He is presently working on the iqClock project and is responsible for ultrastable optical frequency transfer.


Vijay is an alumnus of Newton International Fellowship and he also serves as a reviewer for the European Physical Journal D.
