Music

Music.

I write, record, and release my own music. The creative outlet that keeps everything else honest.

Dog DNA

Pawternity
Test.

Yes, your dog has cousins. No, they don't text back either.

I led the development of Relatives at Wisdom Panel, bringing ancestry-style discovery to pets and helping owners explore their dog's genetic connections.

Climbing

Conquering
heights.

I have a fear of heights. Nothing makes progress easier to measure than routinely climbing up cliffs.

Ceramics

Ceramics.

Throwing, hand-building, and glazing. The physical counterweight to digital work — you can't undo a bad pull on the wheel.
