Eight Students Complete Mid-Term and Proposal Defenses

On October 17th and 18th, eight students from our research group successfully carried out their mid-term defense and research proposals. Yingjian, wanzhe, siqi, xiaosong and zibing shared the progress over the past year, detailing key milestones and insights from their research. In addition, three master’s students, Xueling, Hangyi, and Yuxin, successfully presented their research proposals. These sessions provided a comprehensive overview of the ongoing projects and future research plans. The presentations were evaluated by an esteemed panel of experts, including Professor Zhang Gan, Zhao Shizhen, Li Jun, Zhong Guangcai, and Mo Yangzhi. The feedback and insights from the panel were invaluable in guiding the next steps of the research.
