Professional Experience

  • Research Assistant / Scientist 1 CIRES CU Boulder/NOAA 2017-2019

Graham Feingold and I integrated aerosol number concentration observations into a Large Eddy Simulation system for modeling shallow cumulus clouds, then created a database of aerosol-cloud interaction (ACI) simulations constrained by observations. We analyzed this by combining a new application of mutual information theory with a framework supported by previous literature. We learned how to account for sub-cloud-scale spatial hetereogeneities when calculating the radiative effects of ACI, potentially reducing systematic analysis errors, producing at least 3 publications (currently in revision / review).

  • Research Assistant, University of Utah 2010-2017

Professor Steven K. Krueger and I studied cumulus parameterization evaluation, cumulus updraft and downdraft structure, and new analysis techniques for numerical models of convection, producing numerous talks and directly at least 2 publications.
