Youcheng Liu

Dr. Liu trained in medicine at Nanjing Medical University and Public Health at Peking University Health Science Center in China. He further obtained an M.S. in Environmental Health and an ScD in Industrial Hygiene and Epidemiology from Harvard University. He completed postdoctoral residency in occupational and environmental medicine studies at Yale University School of Medicine.

Prior to joining Wayne State University, Dr. Liu was an Associate Professor in the School of Public Health at the University of North Texas Health Science Center. He also held positions of Assistant Professor of Medicine at Yale University School of Medicine and School of Public Health, and of Assistant Professor of Preventive Medicine and Environmental Health at the University of Kentucky College of Public Health.

Research interest(s)/area of expertise

Dr. Liu’s research has focused on assessing environmental and occupational exposures to chemical hazards and biological agents, evaluating the resultant health outcomes (such as asthma, COPD, cardiovascular diseases and diabetes) and identifying effective and feasible measures and strategies to reduce exposures and prevent related diseases. He has conducted collaborative research in China, Guatemala and the U.S.

Research

 His research has been mostly funded by governmental agencies such as National Institutes of Health (NIH)/National Heart, Lung and Blood Institute (NHLBI), Centers for Disease Control and Prevention (CDC)/National Institute for Occupational Safety and Health (NIOSH), and United States Environmental Protection Agency (US EPA). Current research projects include dermal exposure to nicotine in migrant tobacco farm workers in Kentucky and the development of a barrier cream and other intervention methods to reduce exposure and green tobacco sickness, isocyanate exposure in neonates, and the identification of user barriers of Powered Air-Purifying Respirators (PAPRs) and evaluation on feasibility and effectiveness of rapidly training and fit testing on elastomeric half-mask respirators in healthcare workers.
