In behavioral health, epidemiologists study patterns of mental illness, substance use, and related health issues in communities across Ohio. They collect and analyze data to find out what’s causing problems, who is most affected, and where help is needed most. Their research helps health leaders, schools, and government agencies make smart decisions—like creating new programs, improving services, or changing policies—to support better mental health for everyone.
