Following their Ph.D., they pursued postdoctoral research at Leibniz Universität Hannover, Germany, under the mentorship of Prof. Herbert Pfnür. Priyanka's work there focused on surface science, particularly the structural and transport properties of thin films and atomic wires (notably Au-atomic wires on Si 553 surfaces). Subsequently, she joined the Centre for Quantum Nanoscience at the Institute for Basic Science (IBS, QNS) in Seoul, South Korea, where she worked with Prof. Andreas Heinrich. The research involved using scanning tunneling microscopy (STM) and atomic force microscopy (AFM) to study the quantum coherent control of spin qubits on surfaces.

Currently, Priyanka is a senior researcher at Johannes Gutenberg University Mainz (JGU Mainz), Germany, working with Prof. Jure Demsar. Their research here focuses on ultrafast phenomena in advanced solids, including strongly correlated electron systems, multiferroics, superconductors, and organic semiconductors.
