Tian Guo is a researcher affiliated with the National University of Singapore (NUS). He serves as a Research Fellow in the Department of Electrical and Computer Engineering within the College of Design and Engineering. Working in the research group led by Professor Ho Ghim Wei, Guo has contributed to projects involving advanced materials for bioelectronics applications. In 2026, he was the first author on work developing a metahydrogel platform and wearable sensor technology capable of decoding fatigue and stress signals from body movements in real time. The research team, including collaborators such as Dr. Pan Xinglong and Dr. Li Zhiwei, demonstrated the sensor's potential for tracking physical and mental health indicators during activity.
