Research Interests: Dr. Cicero-Fernandez is an Adjunct Assistant Professor and the Manager of the Specialty Vehicle and Engine Testing Section at the Haagen-Smit Laboratory of the California Air Resources Board. Research topics include the following: 1) analyses of the effectiveness of air pollution controls in Mexico by studying human exposure assessment using GIS, robust estimation of air quality trends including meteorology and exposure assessment, and the scenario evaluation for future control measurements; 2) control of episodic emissions from mobile sources during extreme conditions and developing and evaluating on-board emission measurements, and in-use evaporative emissions by substituting emission control devices; 3) development of the emission inventory including the impact of humidity on the NOx using GIS and evaluation beyond a flat earth by assessing motor vehicle episodic emissions due to high load driving and positive grades, and a methodology to account for fixed point mobile source emissions; 4) estimation of non CO2 gases impacts and controls for global climate change such as the evaluation of refrigerant emissions of different classes of light-duty vehicles; 5) characterization of in-vehicle exposure measurement and modeling, and PM characterization from non-passenger sources such as off-road engines and alternative fuels, including biofuels.
