Di Zhu received his B.Eng. (2013) from Nanyang Technological University, and M.Sc. (2017) and Ph.D. (2019) from Massachusetts Institute of Technology, all in Electrical Engineering. After graduation, he spent two years at Harvard University as a postdoctoral fellow. His PhD thesis focused on superconducting nanowire single-photon detectors, and postdoc research centered around lithium niobate integrated photonics. In 2021, he returned to Singapore and worked as a research scientist and principal investigator at the Institute of Materials Research and Engineering (IMRE), A*STAR. In September 2023, he joined the Department of Materials Science and Engineering at National University of Singapore as a Presidential Young Professor. He was a recipient of the National Research Foundation (NRF) Fellowship, Harvard Quantum Initiative (HQI) Postdoctoral Fellowship, and MIT Jin-Au Kong Thesis Award.
