Developing novel theory and methods for understanding the genetic architecture of complex human traits (R21)

Funds the exploratory version of the same theory-and-methods work on complex trait variation, for ideas that need testing before a larger project is justified.

This is the exploratory twin of the National Institutes of Health notice on the genetic architecture of complex traits. Same question, smaller mechanism.

The goal does not change: theory and methods that better delineate how genetic and non-genetic factors contribute to variation in complex traits across individuals, families and populations.

Nor do the three requirements. Interdisciplinary acro

Exploratory development of novel theory and methods delineating how genetic and non-genetic factors contribute to complex trait variation across individuals, families and populations, interdisciplinary across the natural and social sciences, accounting for interdependencies across biological, social and ecological scales, using theory, simulations and validation against existing large-scale datasets. Clinical trials are not allowed.
