Disentangling multivariate relationships between cognition, language and social traits: structures of G, E, and rGE

The paper models shared genomic and environmental influences on cognitive, language, and social traits in children, identifying distinct domains with trait-specific correlations between genetic and environmental factors.

Structural models of genome-wide covariance identify multiple common dimensions in autism

The paper uses structural equation modeling to identify three genetic factors linked to language/cognition, behavior, and motor development in ASD, revealing novel associations and simplex-specific genetic overlaps.

The neutral frequency spectrum of linked sites

The paper derives the conditional Site Frequency Spectrum for a genomic region linked to a focal mutation and presents formulas for neutrality tests in non-recombining regions.

The third moments of the site frequency spectrum

This paper computes the third moments of the site frequency spectrum and derives analytical results for the bias of neutrality tests.
