Seroepidemiology, Clinical Trial Design, and Causal Inference
About
Dr. Arnold's NIH-funded research focuses on seroepidemiology — using antibodies in blood to measure infectious disease transmission, with particular attention to trachoma elimination and enteric pathogens. His work also addresses methodologic questions in applied statistics, clinical trial design, and causal inference.
He heads Proctor's Data Coordinating Center and supports faculty across the Foundation in the design and analysis of more than 20 ongoing randomized controlled trials, principally in Africa and Asia.
