My name is Ziwei Zeng. I graduated from Shanghai University of Sport last year with a major in sports rehabilitation. Currently, I am a first-year PhD student in the Department of Sports Science and Physical Education at CUHK. My previous research focused on running performance and wearable sensor technology, and I have published several SCI papers on this topic during my master’s programme. However, given the global concern about aging, I am now inclined to study topics related to the elderly, particularly those with mild cognitive impairment.
