Prior to his appointment, he obtained his B.Sc. in electronics engineering from the University of Science and Technology of China in 2016. Later, he completed his PhD in biomedical engineering and MEMS/NEMS technology at the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, followed by one year as a visiting PhD at Stony Brook University. In 2021, Yujia joined the Bayley group and later became an early-career research fellow hosted in the Department of Chemistry at the University of Oxford.

Research
Bioiontronic synthetic tissues
The research group is highly interdisciplinary. There are three main research directions:
- Advanced manufacturing of iontronic synthetic tissues—3D printing system to construct microscale, multimaterial hydrogel droplet networks.
- Multifunctional iontronic synthetic tissues from patterned droplet networks, including functions of embodied energy, logic control, stimuli-responsiveness, therapeutics delivery, etc.
- Modulation of living cells in culture. Examples include human iPSC-derived neurons, cardiomyocytes, and organoids.

Teaching & PhD
PhD Students
Courses
MOOC: Micro and Nanofabrication (MEMS)
MICRO-621(a)
Micro- and nanofabrication can be taught to students and professionals by textbooks and ex-cathedra lectures, but the real learning comes from seeing the manufacturing steps as they happen. This MOOC will not only explain the basics of microfabrication but also show the practice through videos.
MOOC: Micro and Nanofabrication (MEMS) - Spring
MICRO-621(b)
Micro- and nanofabrication can be taught to students and professionals by textbooks and ex-cathedra lectures, but the real learning comes from seeing the manufacturing steps as they happen. This MOOC will not only explain the basics of microfabrication but also show the practice through videos.
Microfabrication technologies
MICRO-331
The student will learn process techniques and applications of modern micro- and nanofabrication, as practiced in a clean room, with a focus on silicon, but also multi-material microsystems and flexible/stretchable systems technologies.
