Research Interests:

Germline stem cells
We study mechanisms that regulate the development and function of germline stem cell in zebrafish, with a main focus on female germline stem cells. We study factors that function within the stem cells, as well as those that are required for the development of the somatic gonad, the germ cell niche.

Sex determination and maitenance of the adult sexual phenotype
While zebrafish do not switch sex as adults, our lab has recently discovered that maintenance of the adult female sexual phenotype is an active process that requires continuous input from germ cells, as reduction of germ cell numbers in an adult female results in female-to-male sex reversal. Our current research is focused on determining what signal is produced by the germ cells and how it influences the developmental state of the somatic gonad.
