The people behind your review
Meet Our Methodologists
Your systematic review or meta-analysis is led by a named PhD methodologist or biostatistician with real credentials and published work. Here are some of the people who do it.
Wei Cheng, PhD

Wei Cheng holds a PhD in Biostatistics from Brown University, where his doctoral research developed network meta-analysis methods for diagnostic accuracy studies. He leads network meta-analysis, diagnostic and prognostic accuracy reviews, and Bayesian evidence synthesis, and is the author of multiple published systematic reviews and network meta-analyses. He takes on the most complex indirect-comparison and quantitative synthesis work.
Eva Culakova, PhD

Eva Culakova brings more than twenty years in clinical and oncology biostatistics and a PhD from the University of Rochester. She has served as study statistician on multi-site randomized controlled trials, with deep experience in systematic review and meta-analysis, survival analysis, risk-prediction modeling, and grant methodology for nationally funded research. She provides senior statistical oversight on clinical-trial-grade deliverables.
