Research Interests: Our lab studies the regulation of chromosomes segregation during cell division in higher eukaryotes and the contribution of centromeres and kinetochores in this process. We use a variety of molecular, cell biological, biochemical, and genetic approaches. We are also interested in determining how our findings apply to humans, and to diseases related to chromosome dysfunction, such as mental retardation and cancer.
