  • Faculty Affiliate, Crime and Justice Policy Research Program


Dr. Marizen Ramirez is an epidemiologist with over 20 years of experience in conducting research on injury, violence and disaster preparedness particularly in underserved, high-risk minority populations including children, racial/ethnic minority groups, workers and rural populations. Her work spans the full spectrum of descriptive to etiologic to intervention and translational research. She has led descriptive and etiologic studies utilizing secondary datasets (e.g., school insurance and police/security records, coroners records, hospital/medical records, department of transportation data, population-based surveys such as the Youth Behavioral Risk Surveillance System) on a variety of topics such as school injuries, earthquake-related injuries, traffic injuries, agricultural injuries, and violence in schools and the workplace. She has conducted quasi-experimental and randomized controlled trials to evaluate interventions such as laws and policies in schools and in the workplace, disaster preparedness programs in rural communities, and Trauma-Informed Care interventions for child victims of trauma. Her diverse funding portfolio includes grants from the Centers for Disease Control and Prevention, the National Institutes of Health, the Patient-Centered Outcomes Research Institute, the National Institute of Justice, the US Department of Agriculture, and the Robert Wood Johnson Foundation. Currently, she serves as Director of the Midwest Center for Occupational Health and Safety, which trains the next generation of occupational health professionals.
