Sihui Peng began her doctoral studies at Zhengzhou University in 2023 under the supervision of Prof. Yanlin Song and Prof. Pengwei Li. Her research focuses on the structural design, crystal synthesis, and application of low-dimensional metal-organic-inorganic perovskite materials in optoelectronic devices. In July 2025, during her Ph.D. program, she joined Park group at NUS as a visiting student. She will study the precise control strategies for the distribution of widths in two-dimensional perovskite quantum wells and apply these strategies to optoelectronic devices.
