On April 27, the 2025 “Electro-Optic Rising Stars” Undergraduate Academic Exchange Conference, jointly organized by the Department of Electrical Engineering and Applied Electronics (EEA) at Tsinghua University and the Department of Physics of the School of Materials Science and Engineering at Beijing Jiaotong University, was held at Lecture Hall 3-217, West Main Building, Tsinghua University. The conference brought together over 70 experts, scholars, and outstanding students from the fields of electrical engineering, optoelectronics, and physics from both universities. Through academic presentations, poster displays, and interactive discussions, the event provided a platform for academic exchange, stimulated research innovation, and promoted interdisciplinary collaboration and inter-university cooperation. The meeting was chaired by Professor Sun Hongyu, Assistant Dean of the Physics Department at Beijing Jiaotong University.

Opening Remarks

Professor Yu Zhanqing, Deputy Secretary of the Party Committee of EEA, and Professor Li Jiakun, Deputy Director of the Physics Department at Beijing Jiaotong University’s School of Materials Science and Engineering, delivered opening remarks. They emphasized the close connection between Tsinghua’s Class 33 in Electrical Engineering and Beijing Jiaotong University’s Optoelectronics Class 2303, encouraged students to cherish this opportunity, boldly showcase their academic talents, actively engage in intellectual exchange, and wished the conference great success.

Expert Presentations

Four invited experts shared breakthrough research results and cutting-edge industry developments in innovative fields including integrated energy, quantum metrology, and optoelectronic detection, opening new scientific horizons for participants.

Dr. Wang Bin, Associate Researcher at the EE Department, Ministry of Education’s Young Changjiang Scholar, and member of China’s 41st Antarctic Expedition team, gave a talk titled “Key Technologies for Clean Energy Utilization in Antarctica: Thoughts and Exploration.” Drawing on his rich experience in Antarctic scientific expeditions, he analyzed the importance of clean energy research in Antarctica, introduced the construction and operation status of China’s Antarctic research stations, and showcased China’s outstanding achievements in polar research. His report broadened academic perspectives and inspired young scholars to pursue clean energy research.

Dr. Li Shisong, Assistant to the EE Department Chair and recipient of the Overseas Young Talent Award, delivered an excellent academic presentation on “Quantum Electromagnetic Metrology.” As a distinguished young scientist in electromagnetic measurement, Dr. Li systematically explained the core technical breakthroughs and development trends in quantum electromagnetic metrology. He especially emphasized the strategic significance of strengthening fundamental quantum metrology research and improving the national metrology system amid intensifying international technological competition.

Professor Li Jiakun reported on “Key Technologies for Measuring Wheelset Geometric Parameters.” Starting from the critical role of high-speed rail wheelsets, he systematically introduced the team’s innovative methods including multi-line laser vision measurement and high-precision camera image analysis. He also analyzed the current development of the high-speed rail inspection market and forecasted future trends in intelligent and automated inspection technologies. He highlighted that as China’s high-speed rail network expands, higher demands for wheelset inspection technologies present both challenges and opportunities for technological innovation.

Dr. Peng Lisha, Deputy Director of the EEA’s Institute of New Electrical Technologies, presented “Applications of Nondestructive Testing Technologies in New Power Systems.” She provided an in-depth analysis of cutting-edge technologies in intelligent detection of power equipment. Dr. Peng systematically introduced innovative applications of various advanced nondestructive testing techniques for diagnosing power equipment defects, especially sharing her team’s breakthroughs in magnetoacoustic testing and electromagnetic ultrasonic guided wave methods.

Student Presentations

In the student session, Shen Yan, recipient of Tsinghua University’s Challenge Cup Special Prize, and Deng Kaihang, principal investigator of a Youth Academic Basic Research project funded by the National Natural Science Foundation, delivered presentations titled “Flexible Control Technology for Air Conditioning Load Based on Virtual Power Plant” and “Power Grid Model Generator Based on Large Language Models,” respectively. They demonstrated the innovative thinking and research capabilities of young scholars in the field of electric power and energy.

Outstanding students Dong Jingqi and Ling Peijie from Beijing Jiaotong University presented research progress and results of their national-level university innovation training projects: “Rapid and Accurate Imaging Method for Bolt Cracks in Wind Turbine Towers Based on Ultrasonic Spiral Phased Array” and “Digital Twin Development Based on Spectral Confocal Displacement Sensor,” respectively, showcasing the practical abilities and spirit of sophomore students.

Poster Exchange

In addition to the exciting presentations, a relaxing tea break and poster exchange session allowed students to gather at the poster display area. While enjoying exquisite refreshments, they engaged in lively discussions with researchers from various project groups.

To encourage academic exchange, an “Outstanding Poster Award” was specially established for interactive voting. After counting votes on site, six posters with exquisite design and solid content were selected. Professors Li Jiakun and Peng Lisha awarded academic scholarships to the winning students.

This poster exhibition of knowledge and inspiration not only provided students with a stage to showcase their research achievements but also built a bridge for interdisciplinary exchange. Many students found like-minded research partners and gained valuable academic advice here. This joy of exchange will surely continue to motivate everyone on their research journeys!
