Research Interests
Professor Dhaniyala's research interests are in developing techniques for accurate characterization of airborne particle properties and understanding the fate of aerosol particles in the environment.
Some of his current funded research projects include: measurement of physical properties of aerosol particles from airborne platforms; fast measurements of aerosol hygroscopicity, development of novel aerosol sensors for large spatial-scale measurements, characterization of filter performance under low-pressure, and fundamental studies of particle resuspension from non-smooth surfaces.
Funding sources for these research projects include: NSF, NASA, NYSERDA, Pall Inc., and DTRA.
