Using insects to understand
how genomes evolve

We investigate why genomes vary so dramatically across the tree of life — in size, organization, and sex chromosome structure — using insects as our primary model system.

Evolution, Genomes & Insects

About Dr. Hjelmen

Genomes vary enormously across the tree of life — not just in which genes they carry, but in the total amount of DNA, chromosomal organization, and chromatin structure. Some grasshoppers carry 7× more DNA than humans. We want to know why. Using comparative phylogenetic approaches, flow cytometry, and whole genome sequencing, active research directions include:
