David Fung, PhD, CIH
Managing Health Scientist
Dr. David Fung is a board-certified industrial hygienist and Supervising Health Scientist with CTEH. His principal areas of training and expertise include air pollution, indoor air quality, industrial hygiene, and exposure assessment. Dr. Fung received his MS in industrial hygiene from UCLA in 2006. He then completed his PhD in Environmental Health Sciences at UCLA in 2012, where his principle research focus involved identifying and characterizing sources of ultrafine particles in indoor and outdoor environments. Dr. Fung continued as a Post-Doctoral Fellow at UCLA where he researched indoor generation of secondary organic aerosols (SOAs) from consumer products such as insect repellent and scented markers, effect of street design on local air quality, control methods to reduce in vehicle exposure to ultrafine particles, as well as the characterization of nanoparticles emitted in electronic cigarettes. He has also performed indoor air quality (IAQ) assessments for classrooms, and offices, where he identified the penetration of diesel exhaust into the school building ventilation system.
Dr. Fung’s industrial hygiene experience include industrial hygiene surveys, exposure monitoring, literature review and analysis, and employee training. Recently, he conducted a state of the art review of the various techniques used to measure and characterize carbon nanotubes released from nanocomposites. In addition, he has provided research and project management support in asbestos, beryllium, and industrial accident litigation. As a consultant, Dr. Fung has also expanded his expertise beyond industrial hygiene, and applied principles of risk assessment to solve issues related to product safety and product stewardship.
In the wake of the COVID-19 pandemic, Dr. Fung has provided support on responses involving cleaning and disinfection protocols, site visits, controls for worker protection, cleaning product recommendations, and more.
