Biostatistics faculty members Tom Fleming and Betz Halloran sit on the WHO Ad Hoc Expert Group on the Next Steps for COVID-19 Vaccine Evaluation.

"This analysis seems to be subject to the Texas sharpshooter fallacy," where someone first fires a shot at a barn then paints a target around the bullet hole, said panelist and biostatistician Scott Emerson, MD, PhD, of the University of Washington in Seattle.

Professor of Biostatistics Jon Wakefield is co-author of a recent paper that notes the explosion in geographic studies in low- and middle-income countries and investigates the extent to which accounting for the sample design affects the predictive performance at the aggregate level of interest for health policy decisions.
