I started by looking for what I couldn't see: the microbes living on my kitchen counter. Years later, I'm still looking. Now it's for what sits underneath medicine: the failed experiment that teaches more than the successful one, the hours of practice no one hears, the family in the waiting room, the decision that has no clean answer.

This is where I write down what I'm learning, and who I'm becoming because of it.

Research
From inflammation to biofilms to cancer cells: what I've studied, and what failure taught me along the way.

Music
9+ years of violin, and what playing for children and teaching younger students showed me about care.

Hard Questions
Euthanasia, parental refusal, scarce resources, and AI in diagnosis: cases I'm still thinking through.
