New hires are required to report onsite for the first 30 days, after which flexible work options may be available at the agency's discretion.
The Texas A&M Transportation Institute (TTI) is an agency of the State of Texas and member of The Texas A&M University System. For 75 years, TTI has addressed complex transportation challenges and opportunities with innovation, objectivity, and unmatched technical expertise. Our staff delivers excellence, value and thought leadership to ensure our research sponsors achieve their goals.

Our Vision - TTI leads in the creation of knowledge that transforms transportation for the benefit of society.

~ Our Mission - TTI delivers practical, innovative and sustainable solutions to improve the movement of people, data and goods through research, education and technology transfer.

Affiliation with Texas A&M University students and faculty

• Ability to help train the next generation of transportation professionals
• Premier office and research facilities and equipment
• Accredited laboratories and safety proving ground
• Outstanding research support services
• Hybrid work environment/telecommuting
• Flexible work hours
• Leadership development and wellness programs
• Data allowance and home office equipment reimbursements
• Relocation assistance (if eligible)

TTI employees can choose from several health coverage options offered by The Texas A&M University System for themselves and their families, as well as numerous other benefit programs.

This position has the flexibility of a hybrid remote option with two days in a TTI Texas based office. A Presidential proclamation issued on September 19, 2025, imposes a $100,000 fee on new H-1B petitions filed after September 21, 2025. Therefore, if you need immigration sponsorship for your employment, we recommend that you consult with your private immigration counsel at your own expense to ascertain whether your current immigration status would make a potential offer of employment from Texas A&M University subject to this fee.

~ In addition, on January 27, 2026, Texas Governor Abbot issued a moratorium on the filing of any new H-1B unless approved by the Texas Workforce Commission. Accordingly, if you will now or in the future require sponsorship for employment visa status this moratorium may affect our ability to employ you should you be selected as the final candidate

The Texas A&M Transportation Institute (TTI) is seeking a postdoctoral research associate to support a four-year multi-country research consortium investigating the health impacts of multipollutant and temperature mixtures, and how these can be modified by real-world and hypothetical policy interventions.
The Postdoctoral Research Associate will work under general supervision of the PI, and play a central role in both coordination of the overall initiative, as well as contributing technically to the activities led by TTI.
The project spans three integrated research arms:
Epidemiology, led by European partners, where we will use four pooled European birth cohorts to study the health effects of air pollution mixtures and heat on childhood asthma and lung function.
Toxicology, led by the Texas A&M School of Public Health, where we will investigate underlying biological mechanisms using standard and novel (mito-QC) mouse models, focusing on mitochondrial damage and airway hyperresponsiveness.
Policy, led by the Texas A&M Transportation Institute, where we will assess how heat and air pollution mixtures may be modified by real-world and hypothetical policy interventions, co-created with stakeholders, and quantify the health and distributional impacts of these policy-driven changes in combined environmental exposures.
The incumbent will contribute to both the scientific execution of the policy research arm, and the operational coordination of the project, including stakeholder mapping and engagement, co-creation and prioritization of policy interventions and scenarios, advanced comparative risk assessment, public health impact modeling, and consortium management. The particular emphasis is on the evaluation of policy-relevant scenarios and interventions (e.g., air quality regulations, temperature mitigation pathways, and local and regional transportation interventions), their impacts on population health and the distribution of these impacts across different subgroups.
The role includes leading and contributing to scientific publications, presentations, policyrelevant outputs, media-ready summaries, and stakeholder-facing materials. The incumbent will work collaboratively and closely with an interdisciplinary, international team across the U.and will support the PI in the coordination of consortium activities.
Continued employment is dependent upon availability of funding and satisfactory performance.
Research (65%)
Conduct advanced research focusing on modeling the health impacts of combined air pollution and temperature mixtures.
Long-term shifts in pollutant mixtures (e.g., Temperature stabilization pathways aligned with international targets (e.g., reductions in traffic-related emissions and associated atmospheric chemistry responses.)
Conduct multi-pollutant comparative risk assessments, including multi-pollutant exposureresponse functions and cluster-based approaches coordinating closely with the epidemiology team.
Perform spatial integration (alignment, upscaling/downscaling) for comparative analyses.
Contribute to publications, research presentations, policy briefs, and technical reports.
Conduct initial stakeholder mapping and develop influence/impact matrices to guide engagement strategies and outreach.
Support the design and implementation of stakeholder engagement activities, including four prioritization workshops across study sites (Utrecht, Barcelona, Bradford, Stockholm).
Contribute to the co-creation and refinement of intervention and scenario pathways, ensuring stakeholder input and relevance to local policy and regulatory contexts.
Project and Consortium Management (20%)
Support the PI in the coordination and day-to-day management of a large, multi-institutional research consortium.
Steering Committee, Data Monitoring Board).
Support in tracking project milestones, deliverables, and reporting requirements in alignment with the grant timeline.
Prepare documentation including meeting reports, progress updates, and dissemination materials.
Support collaborative research development and technology transfer activities.
Provide flexible support to the PI across project needs as they evolve over the course of the grant.
PhD in environmental epidemiology, environmental health, exposure assessment, health impact assessment, or a closely related field.

Strong analytical and quantitative skills, including statistical programming (e.g., R, Python, or similar).
Knowledge of causal inference methods and/or comparative risk assessment approaches.
Familiarity with environmental exposures, including air pollution and temperature variables.
Strong organizational and project management skills, with attention to detail and ability to manage multiple tasks and deadlines.
Ability to work both independently and collaboratively in an highly interdisciplinary and international team environment.
Demonstrated expertise in quantitative data analysis and statistical modeling.
Experience with spatial analysis and geospatial data integration, including use of GIS tools (e.g., Applicants are subject to a criminal history investigation, and employment is contingent upon the institution's verification of credentials and/or other information required by the institution's procedures, including the completion of the criminal history check.
