We are interested in understanding the mechanism of chromosome segregation during cell division. Particularly, we aim to obtain high-resolution mechanistic insights into how centromere assembly and function and RNA-modification activities ensure error-free chromosome segregation. Towards this goal, we employ an integrative structure-function approach combining cryoEM, Crystallography and CrossLinking/MS with proteomics and cell biology.
