The division is divided into three programs—Air Quality, Transportation Modeling, and Environment and Planning. Dr. Zietsman has 30 years of professional experience in the field of transportation engineering with a specialization in air quality, sustainable transportation, transportation planning, and the emerging topic of public health and transportation. Over the past 15 years at TTI, he has been PI of more than 50 research projects, valued at more than $16 million. Two examples of these projects are a $3 million project for EPA on truck idling emissions, a nearly $500,000 project for FMCSA on infiltration of pollutant emissions into truck cabins during idling, and a $200,000 cross-disciplinary project on characterizing exposure of traffic-related air pollution and its associated health impacts on pregnant women. Dr. Zietsman also conceived the idea, raised the funding, and oversaw the development of a $3 million one-of-a-kind emissions testing facility at Texas A&M University. Dr. Zietsman has more than 70 technical publications and has co-authored a book on sustainable transportation. He is a frequent speaker at national and international conferences where he has delivered many keynote addresses including some on the topic of health and transportation. Dr. Zietsman is very active with TRB.

Prior to joining the faculty at JHU, Dr. Fox was an American Association for the Advancement of Science Risk Policy Fellow and a Project Officer on the Board of Environmental Studies and Toxicology at the National Academy of Sciences.
Dr. Michael O. Rodgers has held various research and academic appointments at GT for more than 35 years in the Schools of Earth and Atmospheric Sciences, GT-CEE Public Policy, and the GT Research Institute. Dr. Rodgers’s research focus has been on the development and application of models to complex systems in transportation, energy, and the environment. In GT-CEE, Dr. Rodgers has led the development team for a number of major systems models (e.g., Mobile Emissions Assessment System for Urban and Regional Evaluations for the EPA and USDOT and the Atlanta Heavy-Duty Vehicle and Equipment Inventory and Emissions Study modeling system for heavy-duty vehicle activity estimates). At the GT Research Institute, Dr. Rodgers has led the long running (24 years) Continuous Atlanta Fleet Evaluation that uses remote sensing methods to evaluate short- and long-term trends in vehicle emissions. Dr. Rodgers has served as PI/project director on more than 100 research programs for a variety of agencies including the National Aeronautics and Space Administration, EPA, the National Science Foundation (NSF), the National Oceanic Atmospheric Administration, U.S. Department of Energy, and USDOT.
