Research

My research interests focus broadly on the physics and chemistry governing aerosols (particles/droplets laden gas flows) as well as the application of aerosol technology in developing new methods to characterization nanoparticle size, shape, and surface properties. Specific recent research projects include (i) the application of high resolution differential mobility analysis-mass spectrometry (DMA-MS) to examine heterogeneous vapor uptake by nanometer scale clusters, (ii) the development of a drift tube ion mobility spectrometer (DT-IMS) for the rapid analysis of 1-20 nm particles, (iii) the development of nebulization technologies and utilization aerosol size spectrometers to examined protein binding to nanoparticles, (iv) the development of electrostatic precipitation-electrospray ionization mass spectrometry for organic aerosol chemical analysis, and (v)  the development of data inversion routines for coupled mobility-mass analysis of aerosol particles.
