The aim of our research is to understand the evolutionary causes and consequences of sex differences. We use experimental, genetic and genomic genetic approaches to study signatures of sex-specific selection on phenotypes and genomes, using seed beetles as a model system. The current projects include 1) Testing for association between sex-specific dominance and sex-biased gene expression, using RNA-seq, 2) examining gene expression evolution and 3) allele frequency changes under different forms of sex-specific selection, using RNA-seq and pool-seq, respectively. We are also studying sex chromosome evolution in Bruchids, and for this will sequence three new genomes and transcriptomes to test how X and Y chromosomes have evolved.
