Abstract
My lab studies how genomes evolve within and across diverse species of Caenorhabditis nematode roundworms. To understand how divergence accumulates with the formation of distinct species, we are exploring traits of interspecies hybrids at organismal and molecular levels to decipher how gene regulatory changes in genomes manifest over the course of organismal development.
Two features of special importance and interest, for both diversification across species and reproductive isolation between species, include 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.
