Aerosol and nanoparticle science and engineering, especially particle instrumentation development and filtration solutions to air pollution control.  Research interest has focused on industrial applications of aerosol science & technology and nanoparticle engineering, and on developing instrumentation for generating, sampling and measuring airborne particles. Fundamental topics include aerosol charging & neutralization, aerosol sampling, transport & deposition, and air/gas/liquid filtration. Applied topics include developing protection schemes for EUV technology for clean manufacturing of semiconductors; conducting environmental health and safety studies of nanoparticles in the workplaces; developing high-throughput ElectroNanospray platform to enable nano-formulations of pharmaceutical drugs; designing and implementing large-scale air cleaning systems for mitigating PM2.5 in urban air; and developing novel Gasoline Particulate Filter (GPF) to reduce particle/gas emissions from GDI engines. Since 1991, Pui directs the Center for Filtration Research (CFR) as the leading filtration center with 18 international filtration manufacturers and end users (see web-link below).
