Biography

Dr Puxiang Lai received his Bachelor's degree from Tsinghua University in 2002, Master's from Chinese Academy of Sciences in 2005, and PhD from Boston University in 2011. In September 2015, he joined the Department of Biomedical Engineering at The Hong Kong Polytechnic University as a Tenure-track Assistant Professor and was promoted to Tenured Associate Professor in July 2021.

Dr Lai’s research interests focus on deep-tissue optical focusing, imaging, stimulation, and treatment. Current research projects include, but are not limited to, wavefront shaping, photoacoustic imaging, neuron stimulation, optical computing, and artificial intelligence. His research has fueled more than 80 top journal publications, such as Nature Photonics, Nature Communications, Light: Science & Applications, PhotoniX, Advanced Photonics, Advanced Science, and The Innovation. He has been invited to give more than 90 seminars or invited talks worldwide. Since 2015, his research has been continuously supported by National Natural Science Foundation of China (NSFC), Hong Kong Research Grant Council (RGC), Hong Kong Innovation and Technology Commission (ITC), Department of Science and Technology of Guangdong Province, and Shenzhen Science and Technology Innovation Commission (STIC).

Dr Lai was awarded the 2016-2017 Hong Kong RGC Early Career Award, the 2018/2021 Hong Kong Polytechnic University Faculty of Engineering Research Grant Achievement Award, the 2019 PolyU K.C. Wong Belt and Road Visiting Fellowship Award, and the 2020 Hong Kong Polytechnic University Faculty of Engineering Faculty Research Award. As a recognition for his contribution to the field, currently Dr Lai serves as the Associate Editor of Journal of Visual Computing for Industry, Biomedicine, and Art (VCIBA), Editor of Journal of Innovative Optics in Health and Science (JIOHS), Session Editor of Medicine in Novel Technology and Devices (MEDNTD), Editor of Advanced Photonics Nexus, Youth Editor in The Innovation, Standing Committee Member of the Biomedical Optics Panel in the Chinese Optical Society, Committee Member of the Biomedical Optics Panel in the Chinese Society of Biomedical Engineering, Senior Member of the Optical Society of America (Optica/OSA), and Guest Professor of Southern Medical University (China).
