Research Interest

Our lab investigates the genetics and mechanisms of reproduction, meiosis, and genome maintenance.  A major focus concerns checkpoint mechanisms that detect errors in germ cell development so as to protect against chromosome aberrations and birth defects in offspring. We also study how defects in DNA replication lead to genetic aberrations, developmental abnormalities, and cancer. Finally, we have undertaken a project to identify human infertility alleles in human populations using CRISPR-mediated modeling in mice.
