ORCID: 0000-0002-8594-6940

Self introduction

A final-year Ph.D. student in Department of Biomedical Engineering, The Hong Kong Polytechnic University, expecting to graduate in August 2024.

Scientific research experiences in computational imaging and deep learning models for overcoming optical speckles in biological tissues and retrieving images from speckles, under the supervision of Dr. Puxiang Lai (Associate Professor, ORCID: 0000-0003-4811-2012).

Research papers mainly include the speckle-based cryptosystem for face recognition via deep learning (Advanced Science 2022, IF = 15.1), the parameter-free algorithm for iterative wavefront shaping (Optics Letters 2021, IF = 3.6), optical imaging through spatiotemporally decorrelated speckles via a generative adversarial network (In process), and delocalized information in optical speckles via deep learning-based study (In preparation).
