About
Dr. Liem Pham is a leading expert in automotive emissions measurement, with a primary focus on the gravimetric analysis of particulate matter (PM) from light-duty vehicles. His most influential work addresses a critical challenge in environmental regulation: as PM emission standards tighten—from 3 mg/mi under current Federal and California LEV III rules to a stringent 1 mg/mi in California by 2025—measurements approach the detection limits of the traditional gravimetric method. Pham’s landmark 2018 study, cited 4 times, systematically quantifies the uncertainty inherent in this technique, providing essential data for regulators and engineers. By conducting a comprehensive “filter survey,” he identified the precise limits of accuracy and repeatability, directly informing the feasibility of future standards. This contribution is vital for ensuring that policy targets are both scientifically sound and practically measurable. Dr. Pham’s work bridges the gap between laboratory precision and real-world regulatory enforcement, making him a key figure in the ongoing effort to reduce vehicular emissions and improve urban air quality.
