  • Robert Wunderlich, MS, PE

Senior Research Engineer, Director of the Center for Transportation Safety

Mr. Wunderlich is a Senior Research Engineer and the Director of the Center for Transportation Safety at the Texas A&M Transportation Institute. In that role, he is responsible for leading the Center’s efforts in traffic safety research, policy analysis, education, and outreach. Over the past few years, much of Mr. Wunderlich’s work has focused on understanding the factors associated with traffic fatalities and injuries at the state and national levels and finding ways to lower them and developing tools that allow practitioners to perform effective safety analyses.
In 2019, Mr. Wunderlich received the Burton W. Marsh award for distinguished service to the Institute of Transportation Engineers and the National Highway Traffic Safety Administration’s Public Service Award for his dedication to saving lives on U.S highways by championing data-driven traffic safety initiatives. Mr. Wunderlich is a past president of ITE and was elected as an Honorary Member, ITE’s highest honor, in 2021. He is a licensed professional engineer in Texas, a member of Transportation Research Board Transportation Safety Management Committee and the AASHTO Technical Committee on Geometric Design.

  • Dennis Perkinson, PhD

Research Scientist

Dr. Perkinson is currently a Research Scientist with the Texas A&M Transportation Institute’s Center for Transportation Safety. As program manager from 2003 to 2017, he was responsible for the establishment and management of the Transportation Modeling Program following the retirement of key senior staff and subsequent reorganization. He developed a multi-year multi-sponsor research program focusing on the analysis of vehicle activity in conjunction with regional planning, policy and program evaluation, including being Principal Investigator of several studies of heavy truck activity in Texas (extended idling, port and drayage activity, and long-haul routing options). Recent project work in the Center for Transportation Safety includes extensive interviewing of commercial fleet operators regarding their employer-based driver safety programs (BTSCRP Project BTS-01 – Guidance for Employer-Based Behavioral Traffic Safety Program for Drivers in the Workplace). Dr. Perkinson has also studied the diffusion of innovation, designed programs and strategies for organizational adoption of innovation, and evaluated implementation programs. He holds undergraduate and graduate degrees in sociology from the University of South Florida, an M.S. in transportation from Northwestern University, and a Ph.D. in urban and regional science from Texas A&M University.

  • Emily Martin, MS

Assistant Research Scientist

Emily Martin has a background in planning and implementing programs and leading evaluations for initiatives that aim to improve safety and health. As an Assistant Research Scientist at the Texas A&M Transportation Institute, Emily uses data and stakeholder input to understand road safety issues and identify ways to reduce risky situations and behaviors and increase the likelihood of individuals adopting safe practices. She has particular interest in designing effective, holistic programs that help organizations reach their safety goals.

  • Nishita Sinha, PhD

Assistant Research Scientist

Dr. Nishita Sinha is an Assistant Research Scientist in TTI’s Center for Transportation Safety. Prior to this, she graduated from the doctoral program of Department of Agricultural Economics at Texas A&M University in 2021. Her research interests lie at the intersection of behavioral economics and transportation safety. Observed human behavior is a result of complex interaction between an individual’s intrinsic attributes and the external environment. Understanding the mechanisms that govern these interactions is critical to developing effective safety interventions. Dr. Sinha’s research focuses on methodological as well as policy-relevant questions in the field of behavioral and experimental economics. She uses experimental and observational data in her research to test economic models of behavior change theories and their congruence with safety performance. In one of her recently concluded projects, Dr. Sinha analyzed long-form industry survey data to assess the relationship between risk perception and worker-type in agricultural aviation. In an ongoing project, she is involved in designing a survey aimed toward understanding the role of safety training on work-zone driving performance. Throughout her doctoral studies, Dr. Sinha has successfully conducted studies involving human subjects and quantitatively analyzed multi-dimensional data from a wide variety of projects. She has extensive experience in analyzing both experimental and observational data using structural as well as reduced-form models.
