Dunlei Cheng is an Assistant Professor of Biostatistics at The University of Texas
School of Public Health (UTSPH). Before joining UTSPH, he worked as a biostatistion at
Baylor Health Care System. His methodological research interests are sample size
calculation, Bayesian inferences, and diagnostic tests. He also enjoys collaborations
with other researchers in the health-related fields. His work has been published on the
following peer-reviewed journals: Annals of Epidemiology, Association of Operating Room
Nursins Journal, Biometrical Journal, Baylor University Medical Center Proceedings,
