My research focuses on developing flexible, stretchable, and wearable electronic systems enabled by advanced micro- and nanofabrication technologies. The objective is to bridge semiconductor manufacturing with emerging applications in wearable healthcare, energy harvesting, and intelligent electronic systems.
My primary research areas include:
Flexible and Stretchable Electronics: Development of mechanically compliant electronic architectures using serpentine, origami, and kirigami-inspired designs to improve reliability under bending and stretching.
Thermoelectric Energy Harvesting: Design and fabrication of flexible thermoelectric generators for self-powered wearable sensing systems and low-power IoT applications.
Micro- and Nanofabrication: CMOS-compatible fabrication processes, MEMS technologies, thin-film devices, flexible hybrid electronics, and advanced semiconductor manufacturing.
AI for Electronic Design: Artificial intelligence and optimization algorithms for PCB autorouting, electronic design automation, and intelligent circuit design.
I welcome collaborations with researchers, industry partners, and students interested in flexible electronics, wearable sensing, semiconductor manufacturing, and intelligent electronic systems.
