Research Summary
Cathy joined the Hawley Lab in 2003, following the completion of a PhD at UMKC that focused on the study of a herpes virus. She is both the lab’s Senior Research Scientist and the Lab Manager. Since joining the lab, Cathy’s focus has been on identifying and studying genes required for homolog pairing and recombination during meiosis. Cathy has played a critical role in shaping understanding of the synaptonemal complex. Currently, her research has focused on a set of genes encoding potential E3 ligases that are required for determining DNA double-strand break fate. These genes are both required for the process of creating the DNA double-strand breaks and converting a subset of those breaks into crossovers.  Perhaps most excitingly, these proteins appear to localize to the Recombination Nodule, one of the most fascinating and mysterious structures in the meiotic nucleus.
