Saravanan received his M.Sc. degree in Physics in 2016 from the University of Siegen, Germany where he worked on stabilizing charged micro-particles trapped in a linear Paul trap. Currently he is a PhD student at the doctoral school of Exact and Natural sciences of the Jagiellonian University, Kraków. His research interests are NV magnetometry, nanoscale magnetic imaging at low temperatures and in general, quantum sensing. Presently, he is tasked in developing efficient imaging methods and data processing tools for magnetic imaging using NV centers in diamond. As a part of his doctoral thesis, he envisions in building a cryogenic diamond microscope for imaging high Tc superconductors and 2D materials. In QUNNA project, he is responsible for imaging diamonds deposited on planar structures and use it to obtain magnetic field vector maps. Since June 2021, he is serving as the head of PhD student council of the doctoral school of Exact and Natural sciences at UJ. Apart from research, he enjoys playing badminton, cooking and bird watching.
