I'm a geochemist. In the past ten years I've fixed mass spectrometers, blasted sapphires with a laser beam, explored for uranium in a nature reserve, and measured growth patterns in fish ears, and helped design the next generation of the world's most advanced ion probe. My main interest is in-situ mass spectrometry, but I have a soft spot in my heart for thermodynamics, drillers, and cosmochemistry.

A micromole of photons, moonshine bright
When sand dunes, glac'ers spread across the farm
Migration to a sanctuary's best.
We need an Eden, Oregon lest harm
Befall environments which are distressed.
Six hundred fifty million years ago
The glac'ers covered every continent
Yet benthic evolution did not slow.
How'd life the frozen ocean circumvent?
A diamictite sandwich of black shale
With fossil seaweed as the veg'table.
In open water haven, they prevail
Suggesting snowball Earth was just a fable.
This promised land of cryogenic times.
Requires small, locally mild climes.
