Meridian is a small institution doing serious work. The lean structure is deliberate — it forces clarity about what matters and removes the bureaucratic overhead that slows comparable institutions down. This page is honest about what that looks like today.
Meridian was founded on the working observation that the institutions best positioned to solve global-risk problems are often the slowest to do so — and that small, disciplined teams using modern tools can produce outputs that, until recently, required entire research divisions.
The principal investigator holds a doctorate and a master of public health, with a working background in epidemiology and public health surveillance. The work draws on that training; it is not separate from it. Meridian is operated independently of any federal employment and produces outputs that represent the views of the principal investigator alone.
For full professional background, publication history, and the federal-employment context, see the biography page.
Meridian operates with a deliberately modern toolchain. Each tool plays a defined role in the workflow; the principal investigator owns final judgment on every output. The arrangement is what allows a one-person institution to publish at the cadence and rigor of a much larger one.
“The discipline is what holds the work together. Right now, the team is one person. The discipline is what scales.”
