Laboratory: Germ Cell Biology
My laboratory studies the molecular mechanisms underlying mammalian spermatogenesis and infertility using molecular, cellular, biochemical, mouse genetics and genomics approaches. The lab is broadly interested in genes and pathways influencing germ/stem cell self-renewal, differentiation and fertility with a current focus on the function of Tudor domain proteins and other Piwi-piRNA pathway associated factors in gene silencing, genome stability, epigenetics, stem cell biology and cancer.
