Stacie earned a BS in Agricultural Genetics at Iowa State. After internships in labs at Iowa State, the University of Iowa, and Pioneer Hi Bred International, Stacie began graduate work at Washington University in the lab of Dr. S. Kerry Kornfeld. Stacie’s work on reproductive aging in the nematode C. elegans
was supported by a National Science Foundation Fellowship. Her interest in reproduction led her to the Hawley Lab, where she began a post-doc investigating the mechanisms controlling the segregation of non-recombinant chromosomes in Drosophila females. Stacie showed that non-recombinant chromosomes undergo dynamic movements on the meiosis I spindle while connected by heterochromatic threads. She went on to show that Topoisomerase II is required to resolve the heterochromatic connections between chromosomes. As a research specialist in the lab, Stacie has turned her attention to the regulation of the assembly and disassembly of the synaptonemal complex, the complex that holds chromosomes together during early meiosis to facilitate recombination. This work was spurred by the isolation of a mutation in the gene encoding the E3 ligase Seven in absentia (Sina) that causes the components of the synaptonemal complex to aberrantly self-assemble into large structures called polycomplexes. Stacie is continuing to unravel how polycomplex formation is regulated, the structure of polycomplexes, and how polycomplex formation affects meiotic processes. Stacie has also mentored several interns and junior staff whose work has led to manuscripts on gamma-Tubulin and B chromosomes. She has also assisted in a number of other major lab projects.
