Dr. Seth O’Neal’s research focuses on developing practical and effective strategies to prevent Taenia solium taeniasis/cysticercosis, a preventable cause of epilepsy across much of Latin America, Asia, and Sub-Saharan Africa. His research spans a broad range of disciplines, including field epidemiology, simulation modelling, diagnostics development, clinical and community intervention trials, and implementation research, with active collaborations in UW Department of Global Health. He holds a Visiting Investigator position at Universidad Peruana Cayetano Heredia (UPCH), and served as co-Director for the UPCH Center for Global Health in Tumbes, Peru. Dr. O’Neal is an active research mentor, working closely with trainees from a variety of disciplines and stages, through hands-on mentored research opportunities at the Center in Peru. He trained at Oregon Health & Sciences University (OHSU), where he received his medical degree, residency in preventive medicine, and a Masters of Public Health in Epidemiology and Biostatistics. He is currently on faculty at the OHSU-Portland State University School of Public Health.
