What you need to know
TTI is a Texas-based agency that supports a hybrid work environment. This position may be eligible for a hybrid work arrangement, including remote and in-office work, subject to agency policy, operational needs, and supervisory approval. Details can be discussed during the interview process.
This position may be based at any of TTI's urban offices located in Austin, Dallas, El Paso, Fort Worth, Houston, Laredo, or San Antonio, Texas. The selected office location will serve as the employee's primary duty station. New hires are required to report in person to their assigned duty station for the first 30 days of employment. Following this onboarding period, a hybrid work arrangement may be approved at the agency's discretion, with the assigned office remaining the primary duty station.
A Presidential proclamation issued on September 19, 2025, imposes a $100,000 fee on new H-1B petitions filed after September 21, 2025. Please be advised that Texas A&M University will NOT pay this fee. 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
Job Summary
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.S., Europe and the U.K., and will support the PI in the coordination of consortium activities.
Continued employment is dependent upon availability of funding and satisfactory performance.
Essential Duties and Responsibilities:
Research (65%)
Conduct advanced research focusing on modeling the health impacts of combined air pollution and temperature mixtures.
Conduct atmospheric or source-receptor air pollution modeling to assess intervention and scenario-based exposure changes (e.g., using SHERPA, SHERPA-City.)
Evaluate intervention and scenario-based exposure changes through other methods, including:
Long-term shifts in pollutant mixtures (e.g., decreasing PM2.5, PM10, NO2 alongside increasing O3 and temperature.)
Heatwave-related exposure profiles with elevated O3, ultrafine particles (UFPs), and temperature.
Temperature stabilization pathways aligned with international targets (e.g., limiting warming to 1.5°C under SSP-RCP frameworks.)
Sector-specific interventions (e.g., reductions in traffic-related emissions and associated atmospheric chemistry responses.)
Locally co-developed interventions (e.g., low-emission zones, active transport, and urban infrastructure changes.)
Compile, harmonize, and manage multi-country exposure and health datasets (exposure surfaces, census, demographics, baseline health outcomes.)
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.
Assess the distribution of modeled exposures and health impacts across population subgroups.
Contribute to publications, re
