Research Activities

Sexual reproduction is dependent upon a specialized type of cell division called meiosis. Early in meiosis, homologous chromosomes pair with each other and are physically linked together by recombination. Linkage of the homologous chromosomes is critical for proper segregation of the chromosomes to opposites poles in the cell. Our research is focused on the mechanism of recombination during meiosis.
