Research Interests:
  • Our research vision is to investigate the network of mechanisms that regulate chromosome integrity and inheritance. In humans, errors in these processes are the leading cause of infertility, spontaneous fetal loss and birth defects including Down syndrome. Our group is interrogating two major gaps in the field of meiosis. We are investigating the mechanisms that modulate DNA break distribution and contribute to the inheritance fidelity of short chromosomes. We are also investigating the mechanisms that control DNA repair choices during meiosis that promote biased repair with the homologue and genetic diversity. We utilize a combination of approaches including genetics, genomics, molecular and cell biology with mainly budding yeast as our model organism.
