I am a planetary scientist and PhD candidate at the Lamont-Doherty Earth Observatory of Columbia University. I'm interested broadly in the geophysical controls on icy satellite habitability through laboratory experiments and numerical models.

 

At Lamont, I work at the Rock and Ice Mechanics Lab investigating the mechanical behavior (e.g. friction, bulk viscosity, and permeability) of ice and ice mixtures in the laboratory at icy satellite conditions. The goal of constraining these parameters is to better inform processes (e.g. shear heating, subduction, melt migration) that can potentially transport material to the subsurface oceans and affect the ocean chemistry and habitability. See here for more details of my ongoing work.

​

My long-term research goal is to better understand the potential material exchange processes of icy ocean worlds at both the ice-ocean interface and seafloor and the timescales of these processes- essentially looking at the top and bottom boundaries of the subsurface ocean and looking at what gets through and how. Doing so would constrain the global geochemical fluxes in the ocean and help us determine where these environments might fall between a sterile chemical soup and vigorous Earth-like biosphere.
