Li Wu is a professor of Physics at Nankai University. She received her PhD degree from Institute of Physics, Chinese Academy of Sciences in 2005, worked at RWTH-Aachen University as an Alexander von Humboldt Fellowship-supported postdoc in 2006-2007, and was selected in the Program for New Century Excellent Talents in University of China by Ministry of Education in 2011. She is a member of International Centre for Diffraction Data (ICDD), the member of the X-ray Diffraction Committee of the Chinese Physical Society, and the member of the 8^th Council of the Youth Working Committee of the Chinese Materials Research Society. Her research interest is focused on the photoelectric functional materials and devices.

In recent years, the research interest is focus on the study of photoluminescent materials and mechanoluminescent materials, as well as the mechanism of some abnormal luminescence phenomena. The purpose is to get new single-component tunable-wavelength luminescent materials with stable physicochemical property, environmental friendliness and moderate synthesis condition for white LED encapsulation; To get novel mechanoluminescent materials for stress sensor, anticounterfeiting, and biological imaging. Meanwhile, the research can also enrich the energy transfer theory and deepen the understanding of defects in optical materials, as well as clarify the mechanism of abnormal luminescence. At present, she is taking charge of on going project -The unconventional stabilization and abnormal luminescence mechanism of Mn²⁺ in special crystal field environment (the general project of National NaturalScience Foundation of China).
