Lei Xu

Lei Xu is an Associate Professor at the Department of Engineering, School of Science & Technology, Nottingham Trent University. He leads research in the Advanced Optics and Photonics Group (www.aoplab.com) and serves as Associate Editor for Nonlinear Optics in Frontiers in Photonics.

• PhD in Optics (2014), Nankai University, China
• Postdoctoral experience at Australian National University, University of New South Wales

His research spans multiple areas of nanophotonics and meta-devices, including:

• Energy harvesting via resonant meta-optical systems (solar cell enhancement, infrared imaging)
• Flat optical devices using metasurfaces for advanced nanotechnology
• Bio-photonics applications in diagnostics and wearable sensors
• Tunable meta-devices for precision light manipulation

Recent publications focus on high-Q resonators, quasi-BIC states, and nonlinear frequency generation in dielectric platforms. He contributes to editorial boards of journals like ACS Nano and Nano Letters.
