Sayan is a Postdoctoral Researcher in the Quantum Coherent Device Physics Group. At LLNL, he is setting up an experiment to test and advance 3D-printed ion traps, and explore the possibility of scaling up the platform for ion-trap-based quantum information processing.

Before joining LLNL in 2023, he worked as a Postdoctoral Researcher at NIST Boulder (with joint affiliation at the University of Colorado Boulder), setting up an experiment to measure the 8-eV nuclear clock transition in Thorium-229 using a superconducting nanowire single photon detector (SNSPD). Prior to that, he earned his PhD in experimental AMO Physics in the Netherlands, where he performed optical frequency metrology of trapped hydrogen molecular ions to test theory of simple molecules and determine physical constants.

His research interests include physics that may be explored with an ion trap, focusing on the fields of frequency metrology and quantum information processing.
