Short Biography

Dr. Guo Quan Lim is a Texas A&M Transportation Institute (TTI) assistant research scientist. Dr. Lim earned his M.S. and Ph.D. in mechanical and energy engineering from the University of North Texas in 2015 and 2020, respectively. As a graduate student, Dr. Lim’s research was centered around air pollution monitoring and modeling, as well as exploring machine learning elements for predicting air quality. Before joining TTI, Dr. Lim worked as an air resources engineer at CARB where he served as a technical liaison between disadvantaged communities and CARB’s Office of Community Air Protection. 

Dr. Lim’s expertise includes air pollution analysis, dispersion and photochemical modeling, and visualization. He has experience with stakeholder engagement (state DOTs and MPOs), transportation-related simulations (MOVES), data processing and statistical analysis software (R), geoprocessing (ArcGIS), and interactive visualization (Tableau). Dr. Lim is also frequently engaged in stakeholder interviews and meetings, such as participating in quarterly Texas Working Group (TWG) meetings between various stakeholders. 

Since joining TTI in 2022, he has led several projects, including: developing the 2023 Locomotive and Rail Air Emissions Reporting Requirements Emissions Inventory (sponsored by the Texas Commissions on Environmental Quality [TCEQ]), developing the first emissions inventory the Port of Gulfport, Mississippi (sponsored by the Mississippi State Port Authority), updating a Comparison of Energy Use and Emissions from Different Transportation Modes Using the Latest Available Datasets (sponsored by the American Bus Association Foundation), and led multiple projects under the Texas Department of Transportation [TxDOT] – TTI interagency contract, including developing Quality Assurance Tools for Conformity Travel Demand Models, maintaining and updating the MObile Source Emissions Reduction Strategies [MOSERS] tool, updating conformity pre-analysis consensus plan and reporting templates, etc.
