Dr. Lianne Sheppard is Professor in the UW Department of Environmental & Occupational Health Sciences (DEOHS), Rohm & Haas Endowed Professor in Public Health Sciences at DEOHS and Professor in the UW Department of Biostatistics. In 2021, Dr. Sheppard was named to the Rohm & Haas Endowed Professorship, which supports faculty with expertise in the health impacts of chemical exposures. Her current research portfolio includes several studies of air pollution exposures and their neurotoxicant effects. She has a PhD in biostatistics.

Dr. Sheppard's methodological interests center on observational study methods, exposure modeling, study design, and epidemiology. Her applied research focuses on the health effects of occupational and environmental exposures. She is principal investigator of a NIH-funded training grant called Biostatistics, Epidemiologic & Bioinformatics Training in Environmental Health, and she oversees the SURE-EH training program, a project to promote diversity in the environmental health sciences. She is also co-principal investigator of the NIH-funded Adult Changes in Thought Air Pollution study and of a Health Effects Institute study to better understand the role of exposure assessment design and modeling in inference about air pollution health effects.

Dr. Sheppard provides biostatistical leadership for several projects. She collaborates with DEOHS faculty on air pollution cohort studies, identifying the effects of multi-pollutant exposures as well as manganese exposures. She is a Fellow of the American Statistical Association. In 2021, she was named chair of the US Environmental Protection Agency's Clean Air Scientific Advisory Committee.

Dr. Sheppard is Chair of the EPA Clean Air Scientific Advisory Committee and a member of the EPA Scientific Advisory Board. She currently serves on the National Research Council Committee for the Review of EPA's 2021 Formaldehyde Assessment, as well as the Environmental Sciences Review Panel of the National Institute of Environmental Health Sciences. She is a former member of the Health Effects Institute Review Committee and has served on several EPA scientific advisory panels, most recently for the Carcinogenic Potential of Glyphosate and the Toxic Substances Control Act (TSCA) Science Advisory Committee On Chemicals (SACC) Asbestos Panel.
