Our mission is to apply behavioral economics and data science to develop and test innovative interventions for reducing the public health burden of injury and improve the outcomes of injuries once they occur. 

research areas


We partner with auto insurers to study strategies to reduce distracted driving and developed our own monitoring app to learn more about driver behavior. 


Health System

Decision Making

We use medical record data to yield important insights and improve patient health outcomes and change physician behavior.


We use patient-centered data collection through automated texting to improve pain management needs.


Epidemiology and Disparities in Healthcare

We use large administrative datasets to assess epidemiology of injuries and document disparities in care.


Gun Violence

BeSAFIR and collaborators use data from Emergency Departments to understand the epidemiological trends in gun violence. 


COVID-19 Monitoring Program Evaluation

We work with clinicians and innovation researchers to analyze COVID-19 health system processes and test strategies to improve patient outcomes.
