Sijun Du received a B.Sc. degree (Hons.) in Electronic Engineering from Pierre and Marie Curie University (UPMC), Paris, France, in 2011, and an M.Sc. degree (Distinction) in Electrical & Electronic Engineering from Imperial College London, UK, in 2012. From 2012 to 2013, he was with the Lip6 laboratory at Pierre and Marie Curie University (UPMC). From 2013 to 2014, he was a digital IC design engineer in Shanghai, China. In October 2014, he joined the University of Cambridge, UK, for Ph.D. research, where he spent less than three years submitting his thesis. In 2016, he did a three-month internship in the R&D department at Qualcomm Inc., San Diego, CA, USA. In 2018, he was a visiting scholar at Fudan University, China, for three months. From 2018 to 2020, he was a postdoctoral researcher at the Berkeley Wireless Research Center (BWRC), University of California, Berkeley, CA, USA. In 2020, he joined the Department of Microelectronics, Delft University of Technology, where he is now an Assistant Professor.
He is a Senior Member of IEEE and a Chartered Engineer (CEng). He received the prestigious NWO VENI grant in the 2021 round (AES domain, 1st place in ranking). He is a co-recipient of the 2022 ICECS Best Student Paper award. He is a technical committee (TC) member of the IEEE Power Electronics Society (PELS) and IEEE Circuits and Systems Society (CASS). He serves as the review committee member and session chair in ISCAS 2020, ISCAS 2021, and ISCAS 2022. He serves as the Power & Energy track co-chair for ISCAS 2025. He is a member of the 2023 ISSCC Student Research Preview (SRP) committee.
He has authored and co-authored more than 100 peer-reviewed technical papers and 5 patents. His current research is focused on energy-efficient integrated circuits and systems, including energy harvesting, wireless power transfer, and DC/DC converters used in autonomous wireless sensors for the Internet of Things (IoT), wearable electronics, biomedical devices, and microrobots.
