Since graduating from Sun Yat-Sen University, Shengjie Liu has spent the last two years at The University of Hong Kong as a research assistant in the Department of Physics. His work has been in the investigation of light pollution, examining the link between satellite-observed night lights and night sky brightness.

He also has worked at OneSpace Technology in Chongqing, China, as a remote sensing engineer. In that role, he applied satellite data to map crop types and assess water and air quality.

His publications include:

In the Population, Health and Place program, Shengjie wants to study environmental health problems, including urban heat, light pollution and air pollution to analyze their impacts on residents’ physical and mental health. He is also interested in exploring the way in which high-rise and low-rise built environments affect people’s health, especially during the pandemic.
