Kai-Chung Cheng, PhD

Kai-Chung Cheng is an Assistant Professor in the School of Public Health and in Imperial Valley at San Diego State University. He has also worked as a Research Engineer at Stanford University and a Research Scientist at California Department of Public Health, with more than 10 years of experience in measuring and assessing air pollution and human exposure. He led a cohort study that evaluated the effect of air purifier on indoor PM2.5 and asthma in children for low-income families in Fresno, CA. He investigated 36 Indian casinos in California to assess, in the field, the impacts of indoor smoking on involuntary tobacco smoke exposure. He recently took the lead on a project that evaluated secondhand exposure to marijuana smoke; it systematically examined exposure close to smokers, offering insight into recommended safe distances from cannabis smoking. His expertise also involves technology development. Using indoor positioning, he created a mobile mapping method to track time-varying locations and exposures of occupants inside buildings. He developed a machine learning method to differentiate smoking from other indoor particle emissions, such as cooking and household cleaning.
