Li, Hongxing

Li Hongxing is the vice director of the Division of Drinking Water Hygiene at the NCRWSTG, China CDC, where he was worked for more than 10 years. Dr. Li’s research fields include water, sanitation and hygiene, with a focus on rural areas. Li also focuses on water quality management and related policy research. Supported by UNICEF and WHO, he and his colleagues were the first to introduce Water Safety Plans (a drinking water quality management tool) into rural China, using this tool to manage rural drinking water supplies from source to end users.

In 1996 and 1997, as a key staff member, Li Hongxing participated in the National Rural Drinking Water and Environmental Health Status Survey supported by NPHCC. In this nationwide survey, basic information about drinking water quality, sewage treatment, personal hygiene and other environmental information in China’s rural areas were collected and analyzed. Based on the results of this nation-wide survey, the NPHCC implemented a series of new water and sanitation policies. Li is also responsible the technical management of a nationwide rural drinking water monitoring system. Li also authored series of policy research briefs and reports, such as the Study on the Construction of Rural Drinking Water Safety Guarantee System, and has published numerous articles in English and Chinese language peer-reviewed journals.

Luo, Qing

Luo Qing is an assistant research fellow at the NCRWSTG, China CDC. Since 2003, Luo Qing has been focused on epidemiological theory and applied epidemiological research studies. Qing’s primary research focus is on the application of epidemiological methods for the environmentally-related disease prevention and control.

Luo Qing participated in a large research project on the integrated management of cancer in Huaihe River, China (2011-2016) and also conducted a national rural environmental health monitoring project in China (2011-2016) as a primary participant in the project which was led by National Health and Family Planning Commission of the People’s Republic of China. Luo has also engaged in the study on the risk assessment and management of water quality and investigating the potential for sustainable household drinking-water treatment in China. She assisted with the managed of a household water treatment project in Guangxi Province (2013-2014) and led the management of that’s projects subsequent replication in Henan Province.

Presently, she is working on research studies on environmentally-related disease epidemiology, environmental health related factors, and environmental health policy evaluation systems. 

Ray, Isha

Isha Ray is the co-director of the Berkeley Water Center and an Associate Professor in the Energy and Resources Group at the University of California, Berkeley (UC Berkeley), where she has been since 2002. Professor Ray also serves as a key advisor to UN Women for their sustainable development and water and sanitation programs, is a member of the Portfolio Advisory Panel of Water at the Acumen Fund, and also serves as an Advisory Member at AddVenture.  She has extensive past and ongoing experience in the nonprofit sector on sustainable rural development in India, and international development- and freshwater-related issues. Professor Ray’s research interests are the politics and economics of water allocation and use, common property resource management, and access to water for the rural and urban poor, especially in low and middle-income countries. In addition to her China work, her research projects in India and Tanzania focus on access to water and sanitation for the rural and urban poor, and on the role of technology in improving livelihoods. Prior to coming to UC Berkeley, Professor Ray was an analyst on economics and institutions at the Turkey office of the International Water Management Institute.  

Tao, Yong

Director Tao Yong manages the National Center for Rural Water Supply Technical Guidance (NCRWSTG), a specialized agency of the Chinese Center for Disease Control and Prevention (China CDC). Director Tao primarily conducts work and research on rural drinking water supply, treatment, and health; rural environmental sanitation surveillance; health risk evaluation; and the drafting of related national technical standards.

Director Tao has managed more than ten national research projects, sanitary standard studies, and assessment of national standards and regulations related to environmental health and the like, including national surveys that cover 60-70,000 households. He has also developed and led numerous projects and collaborations with international multi-lateral agencies, such as WHO, UNICEF and ADB on projects related to drinking water, environmental health, and individual hygiene in rural China.
