Education

Self-Intro:

Dr. Haomiao Yu, lecturer and master supervisor of Beijing Jiaotong University, is mainly engaged in the research of flexible optoelectronic devices and mechanisms, including flexible perovskite solar cells, light-emitting diodes, organic solar cells and light-emitting diodes. He has rich experience in material preparation, device design and mechanism research, and has extensive contacts with relevant research groups at home and abroad. He presided over one youth project of NSFC, and participated in one general project and one special project of NSFC as a backbone member. He has published more than ten academic papers as the first author and corresponding author in Advanced Functional Materials, NANO ENERGY, Journal of Physical Chemistry Letters and other world-class magazines.

What I want to say to students: as a young master's supervisor, I hope to help you cultivate the ability of independent thinking and problem-solving in the graduate stage, enjoy the scientific research process and realize your personal ideal.
