Key studies that have shed light on the conservation and divergence in gene expression between species
Mechanisms of speciation and hybrid incompatibility
Natural selection and adaptation
Linking genotypes to phenotypes via gene expression
Ecological genetics
Emerging new types of microarray, and the novel questions they may be used to address.
