Professional Interests

Dr. Wangs overarching research theme is to understand aerosol source, transformation, and impacts. Specifically, his research interests include physical and chemical characterization of aerosols, pollution source characterization, air quality measurement, and aerosol instrument development. His research involves a wide range of instrument design, laboratory method development, field measurement, numerical simulation, and data integration. Dr. Wang has been involved in the development and use of a multitude of instruments for characterizing aerosol properties. He is a co-inventor of the nanoparticle aerodynamic lenses for efficiently delivering nanoparticles into aerosol mass spectrometers and the TSI DustTrak DRX Aerosol Monitor for real-time size segregated aerosol mass concentration measurement. He led the design of the DRI Portable Emissions Measurement System (PEMS) that has been used for characterizing gases and particles from vehicle exhaust, stack emissions, biomass burning, and biomass-derived syngas. Dr. Wang also led the design and development of the DRI Model 2015 Multiwavelength Thermal/Optical Carbon Analyzer. He is leading the efforts to further expand capabilities of current thermal optical carbon analysis to simultaneously measure major elements (C, H, N, S, and O), ions, organic mass to organic carbon ratio, and multi-wavelength light absorption spectra of particles collected on filter samples. Dr. Wang is the principle investigator of ongoing projects to study vehicle fleet emissions in roadway tunnels, and to measure emission factors and source profiles from mining trucks. He conducted real-world multi-pollutant emission characterization from mining fleet, industrial stacks, and fugitive dust sources in the Athabasca Oil Sands Region in Alberta, Canada. He participated in recent projects to study the impact of visibility, air quality, and atmospheric deposition of particles generated from wildfires and prescribed burns in the Lake Tahoe Basin, and the spatial distribution of residential wood combustion emissions in Reno and Sparks, NV. Dr. Wang is an active participant in several scientific organizations. He conducts peer reviews for scientific publications and funding agencies. He served as co-chair and chair of the Instrumentation Working Group of the American Association of Aerosol Research (AAAR) annual conferences and chair of the Young Investigators Committee of the AAAR. Dr. Wang has been granted three patents and published three book chapter and 65 peer-reviewed journal articles.
