Research
My research is focused on microstructural analysis of primarily geologic samples in the Cryosphere. By utilizing X-ray micro-computed tomography, I obtain 3D images from which I can quantitatively characterize the material's microstructure. This include calculations of porosity, degree of anisotropy, pore morphology, surface to volume ratios, structure thicknesses, etc. Below are a few examples of some recent projects:

Brine Channel Morphology in Sea Ice Salts, fluids, and heat travel through the intricate brine channels of sea ice. How can we use mathematical topology to characterize the brine channel morphology? Can we create a network model that can be used as a statistical framework in dynamical sea ice models? |

Transport of Bromine into the Atmosphere in Polar Regions Bromine initiates the breakdown of tropospheric ozone in polar regions. How does bromide and other sea salts enter the atmosphere? What role does blowing snow play in tropospheric ozone photochemistry? |

Weather Forecasting: Shadowing in the Atmosphere A hurricane is threatening to strike the coast. How long until it hits? Where? Is this forecast accurate? How can we increase the time our models are a true representation of reality? |

Studying the Air-Water Interface of Porous Media There is a gas spill threatening to endanger a town's water supply. Where will the gas flow? How long will it be retained in the soil? How do the physical properties of the soil affect the transport of the contaminant? |
