Dr. McLinden holds a Ph.D. in chemical engineering from the University of Wisconsin and joined the National Institute of Standards and Technology in 1984. His research in the NIST Applied Chemicals and Materials Division focuses on highly accurate measurements of fluid properties over wide ranges of temperature and pressure and the design and fabrication of instruments for such measurements. Throughout his career, Dr. McLinden has researched “new” refrigerants; in the 1990s replacements for the ozone-depleting CFC and HCFC refrigerants were the focus, and more recently, his attention has turned to fluids having low global warming potential (GWP). He is the author or coauthor of more than 120 peer-reviewed publications and has received several awards related to his refrigerants research.
