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

    A field that is not mine yet, read closely: I recount a well-known 2009 microbiome chart to show what it measured.

  • The Window Stayed Shut

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

  • 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.

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.

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.

Capped, Not Deleted

A bottle labeled DRINK ME shrinks Alice to ten inches, and a cake stretches her past her own feet, yet at every size she is still Alice. Part two of two: two cohorts who share an ancestry, one that stayed in the Philippines and one that moved to the United States, and a methylation signature that still comes back different, and the diabetes box on a clinic's intake form.

Nothing Grows Alone

Breast milk delivers millions of bacteria a day to a baby, and in 1899 a doctor in Paris saw that it also picks which ones win the gut. Part one of three: milk carries sugars only those bacteria can eat, a recount of a 2009 chart shows what a well-known map of the microbiome measured, a four-day course of antibiotics can leave some of them missing for months, and a 2024 review of the microbiome asks what a body is once its microbes count.
