High-level academic exchanges are an important way to cultivate the innovation ability of postgraduate students. In order to strengthen the academic exchanges among postgraduate students, create a strong scientific research and academic atmosphere, and broaden the academic vision and knowledge of postgraduate students, the School of Physics and Optoelectronic Engineering held the first postgraduate academic forum and outstanding achievement exchange meeting in the large classroom 3100 of Building 21B on the afternoon of November 20. The theme was "Technological Innovation Leads the Future, and the Spark of Wisdom Illuminates Academics". Professor Zhang Yu, the deputy Party secretary and vice dean of the college, attended the event. Ren Yongzhi, the assistant dean, presided over the event, and representatives of postgraduate students from various grades participated.
The forum invited 11 outstanding postgraduate students who won the college's Outstanding Research Achievement Awards in 2024 as keynote speakers to tell other postgraduate students about their academic achievements, research directions, innovative methods, and experiences.
Zhang Yu delivered a speech for this forum. She encouraged the students from three aspects: learning, life, and goals. During the postgraduate stage, they should attach importance to the cultivation of academic thinking and the training of scientific research abilities. In particular, they should pay attention to academic exchanges, focus on the cultivation of their own comprehensive abilities, always maintain good learning and living habits, actively participate in various academic activities, and continuously improve their academic abilities in practice.
