The paper quantifies the evolutionary rate of sex-biased gene expression in songbird brains, finding faster evolution on the Z chromosome and increased rates in species with obligate cavity-nesting.

This paper introduces permutation tests to detect evolutionary features from allele frequency timeseries without assuming a model of evolutionary change.

This paper revisits the mutation-selection balance model by incorporating fluctuating stabilizing selection, showing that heritability predictions are more consistent with observations under environmental change.

CAGEE infers gene expression changes across phylogenies and tissue-specific rates, validated on simulated data and applied to Solanum species.
