Abstract
The viscosity of atmospheric aerosol particles is a key physical property which allows us to predict particle behaviors in the atmosphere including aging, chemistry, and mass uptake. However, viscosity measurements for submicron particles are extremely challenging due to analytical limitations at these extreme sizes. My dissertation work mainly investigates the use of an atomic force microscopy (AFM) based technique to directly determine the melting temperature of aerosol, which can then be converted to viscosity. I have used this to investigate isoprene-derived secondary organic aerosol (SOA), α-pinene-derived SOA, and biomass burning aerosol as well as the effects of factors such as relative humidity and aging on these measurements. My interests include single-particle analytical techniques with a focus on microscopy as well as learning methods to compliment these techniques. I am also passionate about thoughtful data visualization and effective science communication.

I am a Materials/Analytical Chemistry PhD student at the University of Michigan in Prof. Andrew Ault’s lab. My instrumentation experience includes work with microscopy and spectroscopy (AFM, Raman spectroscopy, photothermal infrared spectroscopy). My laboratory experience includes both continuous flow and batch mode chamber experiments as well as experience working in a clean room. I have extensive experience in troubleshooting and fixing a wide range of instrumentation (AFM, aerosol chemical speciation monitor, aerosol mass spectrometer, scanning mobility particle sizers), and I am comfortable problem-solving both experimental setups as well as instrumentation and equipment. I anticipate a defense in May 2026 and I am seeking an academic PostDoc position, and I am flexible in terms of location. I can be reached at kkoloz@umich.edu.
