Broadly, our research interests involve experimental and theoretical electromagnetic (EM) scattering applied to the characterization of man-made and naturally occurring aerosol particles. In collaboration with undergraduate and graduate students, postdocs, and visiting scientists, I have pioneered a digital holographic method to image single particles in a free-flowing aerosol stream and simultaneously measure their scattering patterns. The success of this work has spurred a large-scale study to characterize coarse-mode aerosol (CMA) particle morphology in the atmosphere using a custom made drone-instrument. Below are descriptions of ongoing research efforts that are expanding our investigative abilities of aerosol particles. A breif description of our work in holography is found [here].
