Johnathon P. Ehsani

Johnathon P. Ehsani is an Associate Professor at the Johns Hopkins Bloomberg School of Public Health, with primary affiliation in the Department of Health Policy and Management and joint appointments in Health, Behavior and Society and the Whiting School of Engineering. He is actively engaged in research and teaching related to transportation safety and public health policy.

• PhD, University of Michigan, 2012
• MPH, University of Sydney, 2003
• BS, University of Technology, Sydney, 2000

Dr. Ehsani's research centers on injury prevention and transportation safety, utilizing policy analysis and behavioral research to reduce motor vehicle crashes. His work spans teen driving behavior, distracted driving policies, licensing systems, and the public health implications of emerging mobility technologies such as e-scooters, bike-share, and autonomous vehicles. He employs experimental, observational, and population-based methods, including naturalistic driving studies, to evaluate real-world driver behavior and policy effectiveness. His recent research emphasizes equity in transportation and the integration of public health principles into automated vehicle development.

The 15 most recent publications reflect a strong focus on adolescent driving safety, mental health and driving risk, transportation equity, and the safety impacts of new mobility services. His work combines epidemiological rigor with policy relevance, often addressing vulnerable populations such as teenagers and children in rideshare vehicles. The research spans disciplines including public health, behavioral science, urban planning, and engineering.
