Abstract
My lab studies how genomes evolve within and across diverse species of Caenorhabditis nematode roundworms. To understand how divergence accumulates as distinct species form, we are examining traits of interspecies hybrids at the organismal and molecular levels to determine how changes in gene regulation within genomes manifest during the course of an organism’s development.
Two areas of particular importance and interest—both for species diversification and reproductive isolation between species—are sperm cell biology and small RNA gene regulatory programs. I will present several of my lab’s recent contributions to these interconnected topics, ranging in scale from electron microscopy to community ecology.
