Summary
👤
Senior🎓
Top SchoolPengfei Xu is a Postdoctoral Researcher and device-focused engineer with a PhD in Mechanical Engineering from the University of Toronto and nine years of hands-on experience across mechatronics, MEMS, wearable electronics, and brain-computer interfaces. He combines deep micro/nano-fabrication and process-engineering skills (lithography, sputtering, transfer printing) with mechanical design and FEA expertise to translate lab prototypes into scalable devices. His background spans academia and industry—from developing multi-channel neural interfacing ICs and soft robotic sensors to short-term process engineering at a high-volume display company—demonstrating fluency across materials, circuits, and system integration. Pengfei also contributes to open-source kernel testing (Linux Test Project), improving security-related tests and boundary-condition validation, reflecting a pragmatic, quality-first approach to engineering. Colocated in Zurich, he is adept at leading cross-functional teams to solve interdisciplinary problems that bridge neuroscience, robotics, and semiconductor manufacturing.
