Jun Liu

Principal Air Quality Specialist at BAAQMD

I am an atmospheric scientist and an air quality specialist. I received my Bachelor's degree in Environmental Science and Engineering from Tsinghua University in 2013 and my PhD in Atmospheric Science from UCSD in 2018. My research interests cover various topics in atmospheric science and air pollution, including air quality monitoring instruments and networks, urban anthropogenic particulate pollution, indoor ultrafine particle exposure, and polar and marine air pollution. I hike and enjoy the wilderness in my spare time.
