Profile IntroductionThe nucleus is a crowded environment yet chromosomes are able to undergo a dynamic range of motion through the regulation of gene expression and repair of DNA damage. This problem is particularly acute during meiosis when hundreds of programed double-strand breaks must be repaired at once without chromosomes becoming hopelessly entangled. This choreography culminates in the pairing, synapsis and crossing over between homologous chromosomes. These events in turn are essential for the separation of homologous chromosomes at MI. Research in my lab has focused on studying the chromosome events of meiosis prophase I in budding yeast for over 16 years, where our work and provided mechanistic insight into the progressive nature of forming increasingly stabilized. Recently we have incorporated the zebrafish model into our study of meiotic chromosome dynamic, and we are the first lab study the sexual dimorphic events that occur during meiotic prophase at the molecular level in this genetically tractable vertebrate species.

Meiotic chromosome dynamics
Work in my laboratory explores the dynamic chromosome events that occur during the process of meiosis and how these processes are integrated to achieve accurate chromosome segregation. Chromosome missegregation is one of the leading causes of birth defects in humans. We combine the use of a wide array of tools, including genetics, molecular biology, biochemistry and live-cell imaging using budding yeast Saccharomyces cerevisiae and zebrafish Danio rerio as a model system.
