I develop novel statistical and machine learning methods for scientific questions, and communicate them effectively, whether to a room of domain experts, a classroom of students, or a grant review panel.

Essays

  • Nothing Grows Alone

    The Human Microbiome Project's 2009 chart of bacteria by body part, recounted to show what it actually measured. A field that is not mine yet.

  • Give Me a Screwdriver

    Fisher, twelve potato varieties and a bowl of balls: when a probability is enough to decide, and when you open the machine. My own field, hypothesis testing.

  • The Window Stayed Shut

    Why people live longer than they stay healthy, and why that question has four true answers at once. My research question.

  • Every Candle Still Burns

    A published study rebuilt from public data, with the code in a public repo. Most of it held.

  • The Plaque Was Gone

    An Alzheimer's drug approved for clearing plaque, and the FDA's own statistical review read section by section to see what the trial showed.

  • Put a Pin on It

    The setup behind this site: one file says what is live, so the pages cannot quietly drift from it.

Twenty-Three Cats

Twenty-three cats parachuted into Borneo in 1960 to repair a malaria fix, five definitions of a system, and what systems thinking asks before the next fix: where the cost will show up, and when.

The Thermostat in Your Head

A man who called himself ignorant about his thermostat turned it up high to warm the house faster, like stepping on a gas pedal. Four definitions of a mental model, two copies of one thermostat, and the measured gap that can settle a household argument before the next heating bill.

Zero, One or Two

Sixty seconds after a baby is born, someone gives it a score out of ten. Four definitions of a framework, one doctor's five signs, the death rate that only a rule held still could count, and why twenty job applications sent for twenty reasons cannot say which reason works.

What the Jelly Changed

Its food, not its genes, decides whether a honeybee larva becomes a queen. Twenty thousand human genes, a DNA kit that looks for one key, and a yeast factory that stood idle.

T Always Finds A

Mr. DNA, a mosquito in amber, and frog DNA plugging the holes. Part one of two: the three workers that really read your DNA, and a family phone call that can move a colon screening years earlier.
