Research focuses on experimental study of hybrid quantum systems involving magnon spintronics, integrated photonics, and nanomechanics, aiming at developing high-fidelity quantum transducers for distributed quantum networks. Such interdisciplinary research not only studies the quantum coherent phenomena of individual quantum information carriers but also seeks enhancement of their coherent interactions. Research interests also include developing integrated photonic sensors for biochemical sensing with high sensitivity and specificity, as well as wireless sensor networks in extreme conditions such as in subterranean environments.
