Lingjuan Wang Li is a Professor of Biological and Agricultural Engineering Department (BAE) at North Carolina State University. She began her studies in China with a B.S. in cotton engineering and earned her M.S. and Ph.D. from Texas A&M University in Biological and Agricultural Engineering. She specializes in air quality and animal housing engineering. Much of her research addresses various aspects of air emission problems associated with animal feeding operations (AFOs). In addition to research, Dr. Wang-Li also teaches an undergraduate course in "animal housing and environmental management and a graduate course in "Aerosol Science & Engineering". She has mentored 10 graduate students, of which 4 are Ph.D. students.

Dr. Wang-Li was appointed to the USDA Agricultural Air Quality Task Force (AAQTF) in 2013. She was a recipient of a 2010 National Science Foundation Career Award in Environmental Engineering.  She served as the PI of Southeast Layer Operation for the National Air Emissions Monitoring Study (NAEM) overseen by the USEPA under the “Air Quality Compliance for Animal Feeding Operations. Dr. Wang-Li is a member of American Society of Agricultural & Biological Engineers (ASABE), Air & Waste Management Association (AWMA), International Commission of Agricultural and Biosystem Engineering (CIGR). She was the President (2009-2010) of Association of Overseas Chinese Agricultural, Biological and Food Engineers (AOCABFE), the Editor-in-Chief (2005-2008) of the CIGR Ejournal; Chair (2007-2008) of S1025 USDA Multi-State Research Committee on “Systems for Controlling Air Emissions and Indoor Environments of Poultry, Swine, and Dairy Facilities”.

Dr. Wang-Li's research program has been well-funded by USDA, NSF, EPA and industrial sectors. The College of Agricultural and Life Sciences (CALS) and BAE have made a significant investment in building a new research facility to support animal air quality, environmental control and welfare studies. This facility is equipped with the state-of-art control & monitoring systems for research on improving engineering design, environmental control and air quality to mitigate environmental stresses for enhanced poultry production performance, welfare and adaptation to climate change.
