I am Xia(夏宋鹏程- in Chinese, Pronounce), currently pursuing a Ph.D. degree at Shanghai Jiao Tong University (Ph.D. National Scholarship), focusing on the research of wearable-based human motion reconstruction and human activity recognition. My doctoral journey is under the guidance of Prof.Ling Pei, and meanwhile, I worked closely with Dr.Lei Chu. Previously, I obtained the Bachelor’s degree in Navigation Engineering at Wuhan University (National Scholarship,Outstanding graduates, Top 1% Award of Wuhan University).

Most recently, I am currently deeply engaged in three areas of interest: Motion Capture from Sparse Observations (utilizing IMUs/VR/Radar technologies), Weakly-supervised Activity Segmentation, Motion Analysis for Health purposes, and Embodied Navigation. If you share a passion for these fields or have expertise in related areas, I would love to connect. Please feel free to reach out to me via email at songpengchengxia@sjtu.edu.cn. Looking forward to potential collaboration opportunities. I am also actively seeking faculty and suitable postdoctoral positions.
