• Synthesis and Characterization of Metastable Tetragonal UTe₂ at Ambient Conditions

  My conference poster from the 2024 Gordon High Pressure Conference. Results shown are preliminary and have not been reviewed.

• Unit cell calculator

  A Jupyter Notebook that calculates unit cell parameters (with uncertainties) for a crystal of any lattice system given observed X-ray powder diffraction peaks.

• An Analytical Method for Calculating Metal–Silicate Partitioning

  From an imposed starting composition (and oxygen fugacity) it's easy to determine how much iron enters the metallic phase.

• Basic Principles of Energy-dispersive Spectroscopy

  A simple animation introducing the concept of X-ray EDS. Requires PowerPoint to run.

• Our Laser Heating System

  A detailed optical diagram of the setup for high-temperature experiments at Harvard.

• Basic Figures

  Some simple diagrams appropriate for an introductory geology course.

• Derivation of the Birch–Murnaghan Equation of State

  By far the most useful thing on this site. I couldn't find a worked derivation anywhere, so I made one. Afterwards, I happened across this slightly different derivation by Tomoo Katsura.

• A Mechanically Strong Inner Core Implied by Deformation of Silicon-bearing Alloys

  My conference poster from AGU 2021. Results shown are preliminary and have not been reviewed.

• Martian Core Formation: Implications from the Hf–W System

  My conference poster from Goldschmidt 2019. Results shown are preliminary and have not been reviewed.

• Composition and Seismic Properties of the Martian Interior: A multi-stage model of core formation

  My conference poster from Goldschmidt 2018. Results shown are preliminary and have not been reviewed.

• Deep-Earth Equilibration between Molten Iron and Solid Silicates

  My conference poster from the 2017 AGU Fall Meeting. Results shown are preliminary and have not been reviewed.
