Dr. Candace Tsai is an Associate Professor in the Department of Environmental Health Sciences at UCLA, and the Director/Principal Investigator of the Southern California Superfund Research Program (SCSRP), funded by the National Institute of Environmental Health Sciences (NIEHS). At the Southern California Education and Research Center, Dr. Tsai serves as the Deputy Director of Industrial Hygiene Program. As an expert in industrial hygiene, Dr. Tsai leads research addressing aerosol, nanoparticle and toxic airborne substance exposure assessment in the occupational and environmental settings. She is a Certified Industrial Hygienist (CIH) and has many years of practical experience in industry and business settings. Dr. Tsai has been working on multidisciplinary research projects and collaborates with scientists in the U.S. and internationally. She has applied her expertise in research and teaching, in the fields of health science, aerosol science, toxicology, engineering, human protection, and policy. She serves as a board member in the Sustainable Nanotechnology Organization, as Associate Editor for Journal of Nanoparticle Research, and on the Editorial Advisory Board for ACS Chemical Health and Safety Journal. With her special expertise in nanomaterials, she has served as an expert for the International Organization for Standardization (ISO) and the World Health Organization (WHO) in the nanotechnology programs and she serves as a Threshold Limit Value (TLV) committee for the American Conference of Governmental Industrial Hygienists (ACGIH).

Areas of Interest and Teaching
Dr. Tsai’s research interests address diverse aspects of environmental health and safety, and industrial hygiene - with a special focus on nanomaterials, advanced materials and nanotechnology. Her research involves innovative interdisciplinary collaborations, and she is currently pursuing critical research in exposure assessments, occupational hygiene practices, sampling techniques, engineering controls, and the biological effects associated with various forms of airborne particle exposure. Currently, her primary research activities include:
1) Occupational/Environmental exposure assessments for airborne substances;
2) Particle sampling and sensing techniques for the mining workplace and advanced materials;
3) Personal protective equipment and engineering control techniques for worker protection and pollution prevention including protective clothing, masks, filtration mechanisms, and local exhaust ventilation systems;
4) Interactions of airborne pollutants or nanoparticles with contacting surfaces;
5) Use of computational fluid dynamic (CFD) models for aerosol and virus exposure, and airflow simulation;
6) The biological responses and nanomaterial distributions associated with nanomaterial intake using in vivo and in vitro models; and other topics related to exposure and safety considerations.
Dr. Tsai teaches courses for industrial hygiene discipline and environmental health sciences including industrial hygiene principles, airborne particle, gas and vapor, control methods and ventilation system, emerging technology health and safety and environmental and occupational health introduction courses.
