Elizabeth Anne (Lianne) Sheppard is an American statistician. She specializes in biostatistics and environmental statistics, and in particular in the effects of air quality on health. She is a Professor of Environmental and Occupational Health Sciences and a Professor of Biostatistics in the University of Washington School of Public Health.[1]


In 2016, Sheppard was chosen to chair a panel of the United States Environmental Protection Agency to examine in what quantities nitrogen oxides are harmful.[2] However, in 2018 the Trump administration replaced the Sheppard and other academic experts on the panel with public health officials, at the same time disbanding a related panel on particulate pollution. Sheppard was quoted as saying that these changes would "result in poorer-quality scientific oversight".[3] Sheppard is also a participant in a lawsuit against new agency rules preventing scientists funded by the agency from serving on its panels, a move that caused her to step away from a three-million-dollar grant.[4]


Sheppard graduated from Johns Hopkins University with a bachelor's degree in psychology in 1979, and returned to Johns Hopkins for a master's degree in biostatistics in 1985. She completed her Ph.D. in biostatistics in 1992 at the University of Washington.[1] Her dissertation, Aggregate Data Methods for Relative Risk Parameter Estimation in Diet and Disease Prevention Research, was supervised by Ross L. Prentice.[5]


Sheppard was chosen as a Fellow of the American Statistical Association in 2006, "for contributions to observational studies and environmental occupational epidemiology; for thoughtful commentary in science-policy areas; and for commitment to bringing statistical methodology to elementary and high school education.[6]
