1st Year Director

Jhy-Charm Soo

Dr. Jhy-Charm Soo is an Assistant professor at Department of Biostatistics, Epidemiology and Environmental Health Sciences, Jiann-Ping Hsu College Public Health, Georgia Southern University. Prior to joining the JPHCOPH at Georgia Southern University, Dr. Soo held a research industrial hygienist position in the National Institute for Occupational Safety and Health (NIOSH) for the Centers for Disease Control and Prevention (CDC). He pursued his PhD in Environmental and Occupational Health at National Cheng Kung University, Taiwan in 2011 and received his postdoctoral training from China Medical University, Taiwan in 2012. Prior to work at NISOH, Soo was an adjunct assistant professor in the Department of Safety, Health and Environmental Engineering at Hung Kuang University, Taiwan. Soo was a principal investigator managing a National Occupational Research Agenda (NORA) project funded by NIOSH. He has obtained broad laboratory research and field survey experience in improving sampling and analytical methods for assessment of workplace hazards, especially crystalline silica and VOCs. Soo’s current work focuses on direct-reading instrument and sensor technology that are of key importance for more effectively monitoring aerosol and VOC exposures, which will therefore protect workers by making exposure measurements in real time. In 2015, his pump pulsation study, published in a series of papers, received an Honorable Mention for the prestigious NIOSH Alice Hamilton Award for excellence in Science. He is actively involved in volunteer work with his peers and has served as a Vice-Chair of the Real Time Detection Systems Committee of the American Industrial Hygiene Association. Soo was appointed to the international scientific committee of 11th International Occupational Hygiene Association (IOHA) International Scientific Conference, Washington D.C.
