Xin Liu

A light manipulator

I am currently a Postdoctoral Research Scholar at the Computational Imaging & Mixed Representation Laboratory (WeLight Lab), The University of Hong Kong (HKU).

In 2023, I earned my Ph.D. in Optical Engineering from the X Lab, part of the State Key Laboratory of Extreme Photonics and Instrumentation, within the College of Optical Science and Engineering at Zhejiang University (ZJU). Prior to this, I completed my B.E. in Optoelectronic Information Science and Engineering in 2018 at the School of Physics and Optoelectronics, South China University of Technology (SCUT).

I have a broad interest in Computational Optics, currently with a particular focus on Optics Simulator, Light Shaping, Computational Imaging, Adaptive Optics, Far-field Optical Microscopy (Nanoscopy), and Optical Manufacturing.
