Research interests:

I generally work in the realm of analytical geochemistry on data from electron microscopy, raman spectroscopy, and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)

These are topics that I am interested in:

• Formation and alteration of oceanic crust
• Sediment provenance
• Biosignatures
